Cleanup and simplification of GPUMaterial and GPUPass compilation.
See #133674 for details/goals.
- Remove the `draw_manage_shader` thread.
Deferred compilation is now handled by the gpu::ShaderCompiler
through the batch compilation API.
Batch management is handled by the `GPUPassCache`.
- Simplify `GPUMaterial` status tracking so it just queries the
`GPUPass` status.
- Split the `GPUPass` and the `GPUCodegen` code.
- Replaced the (broken) `GPU_material_recalc_flag_get` with the new
`GPU_pass_compilation_timestamp`.
- Add the `GPU_pass_cache_wait_for_all` and
`GPU_shader_batch_wait_for_all`, and remove the busy waits from
EEVEE.
- Remove many unused functions, properties, includes...

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', ...).

Request one separate compilation batch for each GPUPass so users can
get a better sense of the compilation progress, and to better distribute
texture loading over time.

Move all header file into namespace.
Unnecessary namespaces was removed from implementations file.
Part of forward declarations in header was moved in the top part
of file just to do not have a lot of separate namespaces.

Advanced ID copying code can now take a `new_owner_id` ID pointer parameter,
and use it to set the relevant 'loopback' pointer to its owner ID by the
copy code itself.
Besides avoiding the need for all code copying embedded IDs to set the
loopback pointer themselves, this also means that `lib_id` copying code
itself does not need to use `IDWALK_IGNORE_MISSING_OWNER_ID` anymore.
This change is not expected to have any effect in current codebase.
The goal of this task is to remove noise in the most common material
layering configuration.
Subsequently, this also split the evaluation of different closure to
their own buffer to avoid discontinuity when denoising them.
This commit does a few things:
- [x] Removes use of global for closure random number.
- [x] Refactor the forward evaluation to be closure type agnostic.
- [x] Refactor the gbuffer lib to be closure type agnostic.
- [x] Reduces the number of picked closure to 3 maximum or less.
- [x] Use GPU_MATFLAG_COAT to tag the use of multiple usage of glossy BSDF.
- [x] Use two closure bin for Glossy when more than one.
- [x] Set closure bin per type for best noise level for most materials.
- [x] Change the gbuffer header to put the closure at their bin index.
- [x] Add a method to get a closure from the gbuffer from a specific bin.
- [x] Split lighting passes per Closure.

The term `PIL` stands for "platform independent library." It exists since the `Initial Revision`
commit from 2002. Nowadays, we generally just use the `BLI` (blenlib) prefix for such code
and the `PIL` prefix feels more confusing then useful. Therefore, this patch renames the
`PIL` to `BLI`.

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.
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
