The `pre` handler is called after blender internal code is done populating
the link/append context with data to be processed, and before this data
starts being linked from library files.
The `post` handler is called after blender is done linking, and
potentailly appending and/or instantiating, the requested data and all
of their dependencies.
Both handlers are called with a single argument, the link/append
context.
An new RNA sets of wrappers have been added to expose relevant info from
these internal C++ structures.
NOTE: !113658 is very similar (but tied to asset drag & drop), whereas
this PR is more general (these could probably live hand-in-hand / side-
by-side).
Implements #122357

Some quick py example code:
```python
import bpy
def my_handler_pre(lapp_context):
print("About to {}:\n\t".format("link" if "LINK" in lapp_context.options else "append"),
"\n\t".join("{} '{}', from libs ['{}']".format(item.id_type, item.name,
"', '".join([l.filepath for l in item.source_libraries]))
for item in lapp_context.import_items))
def my_handler_post(lapp_context):
print("{}:\n\t".format("Linked" if "LINK" in lapp_context.options else "Appended"),
"\n\t".join("{} '{}', from lib '{}'".format(item.id.id_type, item.id.name, item.source_library.filepath)
for item in lapp_context.import_items))
bpy.app.handlers.link_append_pre.append(my_handler_pre)
bpy.app.handlers.link_append_post.append(my_handler_post)
```
This replaces the older dynamic c array macros with blender::Vector in
bmesh_polygon_edgenet. This is the only remaining use of the old array
machinery and removal of `BLI_array.h / .c` can happen immediately
afterwards.

Documentation of the `gpu.state.active_framebuffer_get` is inconsistent.
It mentions `framebuffer_active_get`. I believe the cause is that the
C methods in the Python wrapper are named inconsistently.
This PR fixes this by making the wrapper + documentation consistent
with the top level API.

Disable dynamic SDL loading as well as disable SDL for release builds.
This was only used for audio output which can already use OpenAL
if there are back-ends not natively supported by Blender.
- Remove extern/sdlew/
- Remove the WITH_SDL_DYNLOAD build option.
- Remove `bpy.app.sdl.available`.

Accessing `bl_rna` for type defined in `scripts/modules/bpy_types.py`
could return their parent-classes RNA when accessed via their parent
types __subclasses__() method.
The type of an RNA types "bl_rna" should be `bpy.types.Struct`,
it was being set to the type it represented so:
`type(bpy.types.Object.bl_rna) == bpy.types.Object`
which wasn't correct.

This is just not supported, and typically not doable from Blender UI
(since embedded IDs won't be listed in ID template list).
Add asserts to IDProp code itself, and checks & error reports in
relevant BPY and RNA setters.
Use snake style naming for all the kernel nodes functions.
Omit kernel prefix in the names since of the using namespace.
Use full forms of the terms
('iter' -> 'iterator', 'ntree' -> 'node_tree', 'rem' -> 'remove', ...).

API: merged IMB_scalefastImBuf, IMB_scaleImBuf, IMB_scaleImBuf_threaded
into one function IMB_scale with enum IMBScaleFilter {Nearest, Bilinear, Box}
and bool "threaded" param.
Performance:
- Box filtering (nee IMB_scaleImBuf) can be multi-threaded now.
- Nearest filtering (nee IMB_scalefastImBuf) can be multi-threaded now.
Also fix performance regression on float images caused by fix in #126234
- Bilinear filtering (nee IMB_scaleImBuf_threaded) is several times faster now.
Correctness:
- Nearest and Box filtering: no longer loses half of edge pixels when scaling
up.
- Box: fixed garbage results (and possible out of bounds reads) for non-4
channel float images.
- Bilinear: no longer shifts image when scaling up.
- Bilinear: properly filters when scaling down by 2x2.
Test coverage:
- Add gtest coverage for various IMB_scale modes.
- Add a IMB_performance_test performance test, ran manually.
More details, images and performance numbers in PR.

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.

Expose arguments to use when creating a Python sub-process.
Python could fail to start when loaded in a customized environment,
with PYTHONPATH set for e.g. Blender ignores these and loads but a
Python sub-process attempts to use these environment variables which
may point to incompatible Python versions.
Resolve the root cause of #124731.
Calling `foreach_get/set` on a collection property did not trigger
a property update. In the attribute API, this lead to missing
updates after e.g. setting the values of an attribute.
This adds a call to `RNA_property_update` for the getter/setter
bpy rna function and adds a property update callback to all the
different attribute collection properties.

Match function and declaration names, picking names based on
consistency with related code & clarity.
Also changes for old conventions, missed in previous cleanups:
- name -> filepath
- tname -> newname
- maxlen -> maxncpy
No functional changes intended.
This simplifies the arguments for the `delete_keyframe` function.
The `bAction *` was always a `nullptr` so I just removed it.
The rna path char array and the array index were merged into the `RNAPath` struct.

Regression from [0], drivers were tagged as being disabled with a flag
that was never cleared. Causing the label to be displayed for files
where the expressions were enabled and in use.
Resolve by clearing this flag on file load and when re-compiling
expressions - since an expressions block flag may be cleared if it
becomes a simple expression.

This commit moves generated `RNA_blender.h`, `RNA_prototype.h` and
`RNA_blender_cpp.h` headers to become C++ header files.
It also removes the now useless `RNA_EXTERN_C` defines, and just
directly use the `extern` keyword. We do not need anymore `extern "C"`
declarations here.
