So far, when deleting a library (either explicitely, or through e.g.
relocation), its dependencies would get a `nullptr` parent, and
therefore become 'directly used' libraries.
This commit adds a new util to rebuild the libraries hieararchy, and
calls it when a Library ID is deleted.
NOTE: While logic is somewhat similar to what liboverride resync does to
sort the libraries by indirect levels
(`lib_override_libraries_index_define`), there are some key differences
here, notably the fact that if a library has a valid `parent` pointer,
it is not replaced, even if a 'better' parent (less indirect library)
could be found.
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.
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 `Library.tag` data is supposed to be runtime only, so needs to be
cleared when reading data from blendfile.
This fixes the 'need resync' status of a library staying around forever
once set, annoying visual warning in the Outliner.
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.
Part of implementing #105134: Removal of readfile's lib_link & expand code.
This commit adds a new option flag to the lib_query foreach_id code,
which will make deprecated ID pointers to be processed as well.
NOTE: Currently there is no report to the callbakcs about the fact that
it is processing a deprecated ID. This can be easily added later if it
becomes necessary.

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`.
