Move `Library.runtime` to be a pointer, move the related
`LibraryRuntime` struct to `BKE_library.hh`. Similar to e.g.
Mesh.runtime, that pointer is expected to always be valid, and is
allocated at readtime or when creating a new Library ID.
Related smaller changes:
* Write code now uses standard ID writing codepath for Library IDs too.
* Runtime pointer is reset to nullptr before writing.
* Looking up a library by its absolute path is now handled through a
dedicated utils, `search_filepath_abs`, instead of using
`BLI_findstring`.

Previously, values for `ID.flag` and `ID.tag` used the prefixes `LIB_` and
`LIB_TAG` respectively. This was somewhat confusing because it's not really
related to libraries in general. This patch changes the prefix to `ID_FLAG_` and
`ID_TAG_`. This makes it more obvious what they correspond to, simplifying code.

This makes the read and write API functions match more closely, and adds
asserts to check that the data size is as expected.
There are still a few places remaining that use BLO_read_data_address
and similar generic functions, these should eventually be replaced as well.
Pull Request: https://projects.blender.org/blender/blender/pulls/120994
Seems to work OK in basic cases, but needs more work when copying
outside of Main at least.
Note: There is no behavioral changes expected from this commit.
Note that there are at least two known usecases for this change:
* Liboverrides, as with recursive resync and proxies conversion it
often ends up creating 'virtual' linked data that does not actually
exists in the library blend files.
* Complex versionning code (`do_versions_after_setup`) when it needs
to create new IDs (currently handling linked data that way is just not
supported!).
Implements #107847.
The depsgraph CoW mechanism is a bit of a misnomer. It creates an
evaluated copy for data-blocks regardless of whether the copy will
actually be written to. The point is to have physical separation between
original and evaluated data. This is in contrast to the commonly used
performance improvement of keeping a user count and copying data
implicitly when it needs to be changed. In Blender code we call this
"implicit sharing" instead. Importantly, the dependency graph has no
idea about the _actual_ CoW behavior in Blender.
Renaming this functionality in the despgraph removes some of the
confusion that comes up when talking about this, and will hopefully
make the depsgraph less confusing to understand initially too. Wording
like "the evaluated copy" (as opposed to the original data-block) has
also become common anyway.

This data was 'hidden' away in a util in
`lib_query.cc`, which made it hard to discover and keep up-to-date.
However, as shown by e.g. #108407, critical low-level features in ID
management code, such as remapping, now rely on this information being
valid.
Also simplify `BKE_library_id_can_use_filter_id` and
`BKE_library_id_can_use_idtype` to make them more generic, relying on
IDTypeInfo to retrieve IDtype-specific info.
No behavioral changes expected here.
Translation markers `N_()` were added to IDs' plural names in !113912.
I also renamed some of those because I thought there were only display
names.
This commit reverts the renaming, leaving only the addition of the
markers.

Extract:
- Sculpt filter types from the Sculpt menu. Some of these types use a
custom label, different from those defined in the operator RNA,
which was never extracted.
- "Today" and "Yesterday" from the file browser modification date.
- All name_plural from IDs, as these are used in the UI to list which
data block is to be removed, when calling outliner.orphans_purge.
Disambiguate:
- "Area", meaning the measurement of a surface as opposed to a place.

The `lib_link` callback cannot always be fully replaced/removed, as in
some case it is also doing some validation checks, or data editing based
on the result of lib_linking internal ID pointers.
The callback has been renamed for that purpose, from `read_lib` to
`read_after_liblink`. It is now called after all ID pointers have been
fully lib-linked for the current ID, but still before the call to
`do_versions_after_linking`.
This change should not have any behavioral effect. Although in theory
the side-effect of this commit (to split lib linking itself, and the
validation/further processing code) into two completely separated steps
could have some effects, in practice none are expected, and tests did
not show any changes in behavior either..
Part of implementing #105134: Removal of readfile's lib_link & expand code.
The `expand` callback is 'trivial' to replace, since it is only iterating
over ID pointers and calling a callback.
The only change in behavior here is that some pointers that were not
processed previously will now be.
In practice this is not expected to have any real effect (usually
the IDs used by these pointers would have been expanded through other
usages anyway). But it may solve a few corner cases, undocumented issues
though.

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.
Design task: #110784
Ref !110783.
There is no reason at all for each ID read/write callbacks to have to
deal with this generic, common data explicitely. Generic ID read/write
code is the place to handle such data (just like asset, liboverride,
etc. data are handled already).
Note behavioral change expected here.
Also see #103343.
Couldn't move two files yet:
* `softbody.c`: The corresponding regression test fails. It seems like the
conversion to C++ changes floating point accuracy, but it's not clear where that happens exactly.
* `writeffmpeg.c`: Is a bit more complex to convert because of the static array in `av_err2str`.
