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.

All 2D vectors related to image transform code were changed to float2.
Previously, it was decided, that 4x4 matrix should be used for 2D
affine transform, but this is changed to 3x3 now.
Texture painting code did rely on `IMB_transform` with 4x4 matrix.
To avoid large changes, I have added function
`BLI_rctf_transform_calc_m3_pivot_min`.
Main motivation is cleaner code - ease of use of c++ API, and avoiding
returning values by arguments.

This PR explicitly declares integer type for `image_center_offs`, which
formalizes accidentally implemented correct behavior. Previously type
was float, all rhs types in expression were integers, so result was int
cast to float.
Comment is also added clarifying why integer must be used - float may
cause images to be interpolated, even when translation is set to 0.
There should be no functional changes.

Paste and text insert could delete selected text, but then cancel
operator execution due to buffer being too small. Ensure, that operator
returns value based on state being actually changed or not.

`TextVars::text` is only 512 bytes and does not include string ending
byte, and `sequencer_text_edit_paste_exec` uses a very simple truncation
that didn't guarantee valid UTF-8 sequence at the end. This is now fixed
by using `BLI_str_utf8_invalid_strip` after truncating the string.

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.

This commit implements most features needed for simple text editing.
Active text strip can be edited in preview by pressing tab key, which
enabled text editing mode. With this mode active, outline matches text
boundary box and cursor is drawn.
Cursor can be moved with usual keys. Pressing shift starts selection.
Selection and navigation works when text is scaled or rotated. Mirrored
text is not supported in this PR. it can be done, but the text is
unreadable that way, so I kept it simple.
Multi line text is supported. Pressing return key starts new line.
Copy/paste operator uses OS copy paste buffer, so text from other apps
can be pasted.
Text is still limited to 512 characters. Text string property still
exists in side panel and is limited to single line. Individual
characters can not be styled in different way like in 3D viewport, but
the code is mostly ready for such feature.
