This should make VSE code more readable and easier to understand from an
outside perspective.
The name was chosen to be `channel` rather than `channel_index` to keep
things short and concise -- it should be clear based on the context
whether we are talking about the strip's channel index (singular case,
`Strip::channel` or `SeqTimelineChannel::index`) vs. the channel list
(plural case, e.g. `Editing::channels`).

This patch renames `seq1` and `seq2` to `input1` and `input2` in `Strip`
and `StripSelection` structs to consist with recent refactors in
#132179. It also renames other instances of `seq1` and `seq2` (e.g.
local variables) to `strip1` and `strip2` instead.
There is only one small breaking change to the Python API with
`strips.new_effect()` taking in the new names now. There should be
no other functional changes involved.

Ref: #132179
Renames:
- `Editing.act_seq` -> `Editing.act_strip`
- `SequenceModifierData` -> `StripModifierData`
- Its member `mask_sequence` is now `mask_strip`.
- `MetaStack.parseq` -> `MetaStack.parent_strip`
- Remaining function names/parameters that were not dealt with in #132748
- Various references to `seq` or `sequence` throughout code and docs when
referring to a strip
Also moves `_get` to the end of the renamed function names where
applicable for standardization (unless "by" or "from" are used).
There should be no changes to current behavior.

This PR creates 2 namespaces for VSE code:
- `blender::seq` for sequencer core code
- `blender::ed::vse` for editor code
These names are chosen to not be in conflict with each other.
No namespace was used for RNA.
Finally, file `BKE_sequencer_offscreen.h` was moved from BKE to sequencer.

Part of Code Quality Project outlined in #130975.
This patch eschews warning messages urging the user to "select all
related strips" when copying or creating new metastrips and instead
automatically includes those related strips in the operation.
- Attempting to copy or create a metastrip with no strips selected no
longer delivers a warning.
- When copying strip(s), if there are related effect chains, they will
be automatically selected and included in the copy if the operation
succeeds.
- The decision to select related strips was intentional, as it allows
the user to easily see the entire effect chain and thus which strips
were copied.
- When creating a new metastrip, if there are related effect chains,
they will automatically be included in the resulting metastrip.
- This is done using a new
`SEQ_query_strip_connected_and_effect_chain()` iterator. This
iterator is only used for metastrips, and not copying, since the
user may wish to only copy single strips in a connection, but
connected strips should always stay together in a metastrip/seqbase.

When using clangd or running clang-tidy on headers there are
currently many errors. These are noisy in IDEs, make auto fixes
impossible, and break features like code completion, refactoring
and navigation.
This makes source/blender headers work by themselves, which is
generally the goal anyway. But #includes and forward declarations
were often incomplete.
* Add #includes and forward declarations
* Add IWYU pragma: export in a few places
* Remove some unused #includes (but there are many more)
* Tweak ShaderCreateInfo macros to work better with clangd
Some types of headers still have errors, these could be fixed or
worked around with more investigation. Mostly preprocessor
template headers like NOD_static_types.h.
Note that that disabling WITH_UNITY_BUILD is required for clangd to
work properly, otherwise compile_commands.json does not contain
the information for the relevant source files.
For more details see the developer docs:

This renames the struct `Sequence` to `Strip`.
While the motivation for this partially comes from
the "Sequence Design" #131329, it seems like this
is a good refactor whether the design gets implemented
or not.
The `Sequence` represents what users see as strips in the
VSE. Many places in the code already refere to a `Sequence`
as "strip". It's the C-style "base class" of all strip types.
This also renames the python RNA type `bpy.types.Sequence`
to `bpy.types.Strip` which means that this technically breaks
the python API.

Drawing the list of channels on the left side of VSE timeline was taking
surprisingly long time (3.5ms in Sprite Fright Edit v135 on Mac M1 Max).
This PR makes them draw in 0.4ms, i.e. 10x faster, by doing two things:
- Stop "search through the whole timeline" work whenever we need to know
which meta strip (if any) owns some VSE channel. Remember that info in
the "sequence lookup" that already holds data to speedup similar queries
(sequence by name, meta by sequence). I.e. this gains "channel owner by
channel" query hashtable.
- Stop alternating between "regular font glyph cache" and "svg icons glyph
cache" on each channel row, which incurs a draw call / UI batch flush.
Instead, draw all the lock/mute widgets first, then all the channel names.
While at it, simplify code related to sequence lookup:
- Use C++ mutex with lock_guard
- Use BLI Map instead of GHash
- Simplify SEQ_sequence_lookup_tag to just SEQ_sequence_lookup_invalidate
- Remove unused SEQ_get_meta_by_seqbase and SEQ_query_all_meta_strips_recursive

"seq3" input for VSE effect strips has been there ever since
"initial revision" commit in 2002, with comment "pointers voor effecten"
even. But it has never been used, so remove all code that pretends
to do something with it.

This is different from applying effects to regular "source media" strips
like images or movies; an effect "hides" the input strip when it is
below itself in the channel.
Apply the same treatment to Color & Text strips. Fixes#118213.
If someone wants previous behavior for some reason, they can drag
the effect applied on Color/Text to be below the input strip.

Sequencer timeline UI repainting is 3x-4x faster now, for complex
timelines. On Sprite Fright Edit data set, with whole timeline visible
(2702 strips), repainting the timeline UI with all overlay options
(waveforms, offsets, thumbnails etc.):
- Windows (Ryzen 5950X, RTX 3080Ti, OpenGL): 62ms -> 18.6ms (16FPS -> 54FPS)
- Mac (M1 Max, Metal): 39.8ms -> 11.5ms (25FPS -> 86FPS)
This is achieved by:
- Avoiding tiny GPU draw calls (i.e. drawing one quad a time), instead
batch all the quads / lines needed by the timeline display into
series of about-1000 quads per draw.
- For retiming keys display, batch their keyframe point drawing too.
- For audio waveform overlay display, change it to draw batched quads
instead of alternating between line strips and triangle strips. This
actually changes how the waveform looks like (implements #115274)
and fixes some visual issues with waveforms too.
- For fcurve overlays, also draw them as batched quads.
While at it, this also fixes an issue where while dragging strips over
other strips, their text labels would look as if they are behind the
background strips.

Caused by 3fccfe0bc6 again, no idea why these two VertorSet were defined
as static variables in the functions generating them... But this was for
sure calling for _lots_ of problem. There are almost never good cases
for a function to return a static variable, and if it's done, it has to
be done extremely carefully.
Use `VectorSet`, `Vector` or `Span` instead of `SeqCollection` struct.
It is now possible to use native `for` loops and `SEQ_ITERATOR_FOREACH`
macro can be removed.
Another feature is, sets of strips no longer needs to be freed. However,
this poses a limitation, that query functions can not be used in case,
where these sets need to be available outside of scope where they are
created.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
