fbd95c3e53 GPULightmapper: process rays to sky in all bounces as active
Before this change only rays to the sky (RAY_MISS) in the first bounce were
processed as active rays. This caused artifacts, areas were too light, when
more than one bounce were processed.

Now rays to the sky are processed as active rays for all bounces.

7c19684ee9 GPULightmapper exclude back-face triangles while calculating bounces
Edges that are at the edge of a plane, may get behind the scene and will hit
back-face triangles which where included in the lighting calculations. This
caused leaking of light at the edge of planes.

In case a ray hits back-face triangle, it is skipped in the bounce calculations.

e11dd6500a GPULightmapper's triangles and their bounding box will be in-sync
Previously the bounding boxes and triangles were maintained in two separate
arrays (Vectors). As the triangle vector was sorted and the bounding-box array
was not , the order of both arrays differed. This meant that the index in one
was different than the other, which caused lookup issues.

To prevent this, the bounding-box is now part of the triangle structure so that
there is a single structure that cannot become out-of-sync anymore.

cf3f404d31 Implement Binary Shader Compilation
* Added an extra stage before compiling shader, which is generating a binary blob.
* On Vulkan, this allows caching the SPIRV reflection information, which is expensive to parse.
* On other (future) RenderingDevices, it allows caching converted binary data, such as DXIL or MSL.

This PR makes the shader cache include the reflection information, hence editor startup times are significantly improved.
I tested this well and it appears to work, and I added a lot of consistency checks, but because it includes writing and reading binary information, rare bugs may pop up, so be aware.
There was not much of a choice for storing the reflection information, given shaders can be a lot, take a lot of space and take time to parse.

5ad4f26659 Implement the ability to disable classes
* This PR adds the ability to disable classes when building.
* For now it's only possible to do this via command like:
  `scons disable_classes=RayCast2D,Area3D`
* Eventually, a proper UI will be implemented to create a build config file to do this at large scale, as well as detect what is used in the project.

6995b0429c Assorted fixes to UV unwrapping and GPU lightmapper
Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for
context in case of git blame/bisect:

* Fix UV2 unwrapping on import, also cleaned up the unwrap cache code.
* Fix saving of RGBA images in EXR format.
* Fixes to the GPU lightmapper:
	- Added padding between atlas elements, avoids bleeding.
	- Remove old SDF generation code.
	- Fix baked attenuation for Omni/Spot lights.
	- Fix baking of material properties onto UV2 (wireframe was
	  wrongly used before).
	- Disable statically baked lights for objects that have a
	  lightmap texture to avoid applying the same light twice.
	- Fix lightmap pairing in RendererSceneCull.
	- Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`.
	- Port autoexposure fix for OIDN from 3.x.
	- Save debug textures as EXR when using floating point format.

Core: Drop custom copymem/zeromem defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

d3b49c416a Refactor GLSL shader compilation
-Used a more consistent set of keywords for the shader
-Remove all harcoded entry points
-Re-wrote the GLSL shader parser, new system is more flexible. Allows any entry point organization.
-Entry point for sky shaders is now sky().
-Entry point for particle shaders is now process().

99e1ce0690 Invert spotlight angle attenuation
Inverted the spotlight angle attenuation so a higher value results in
a dimmer light, this makes it more consistent with the distance
attenuation.

Also changed the way spotlighs are computed in SDFGI
and GIPorbes and GPU lightmapper, now it matches the falloff used in the scene rendering
code.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

c74d65cec8 GLSL: Change shader type specifier from [vertex] to #[vertex]
The added `#` prevents clang-format from misinterpreting the meaning
of this statement and thus messing up the formatting of the next
lines up until the first `layout` statement.

Similarly, a semicolon is now enforced on `versions` defines to
prevent clang-format from messing up formatting and putting them
all on a single line. Note: In its current state the code will
ignore chained statements on a single line separated by a semicolon.

Also removed some extraneous lines missed in previous style changes
or added by mistake with said changes (e.g. after uniform definitions
that clang-format messes up somewhat too, but we live with it).

07bc4e2f96 Style: Enforce separation line between function definitions
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
  -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
  -o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```

This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.

This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.

Part of #33027.

0be6d925dc Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocks
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.

This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.

There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

Part of #33027.
