112b416056 Implement new CPU lightmapper
Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.

There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.

The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.

This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

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 🎆

glTF: Fix loading external images as buffer
We should first attempt loading as external files, thus creating a dependency.
Loading as a buffer should only be used as fallback to support manually loading
as PNG or JPEG depending on the defined mimeType.

Fixes #44309, was a regression from #42504.

Better non alphanumeric bone names.
1. _gen_unique_bone_name(Ref<GLTFState> state, const GLTFSkeletonIndex skel_i, const String &p_name) won't return an empty string.

2. String GLTFDocument::_sanitize_bone_name(const String &name) will keep Japanese characters. Like: "全ての親".

3. The sanitize function allows  the bone name to be not just alphanumeric. The only required conditions are the ones in add_bone.

> ERR_FAIL_COND(p_name == "" || p_name.find(":") != -1 || p_name.find("/") != -1);

glTF: Fix parsing image data with mimeType undefined
The glTF 2.0 spec only makes `mimeType` mandatory for `bufferView` image data,
so the previous logic to handle URIs with base64-encoded images could fail if
`mimeType` is undefined.

The logic was documented and refactored to better handle the spec, notably:

- `uri` and `bufferView` are now mutually exclusive, and only the latter fails
  if `mimeType` is undefined.
- `uri` with a file path will now respect the `mimeType` if defined, and thus
  attempt loading the file with the specified format (even if its extension is
  not the one expected for this format). So we can support bad extensions (PNG
  data with `.jpg` extension) or custom ones (PNG data in `.img` file for
  example).
- `uri` with base64 encoded data will infer MIME type from `data:image/png` or
  `data:image/jpeg` if it was not documented in `mimeType` initially.
- `uri` with base64 encoded data, no `mimeType` and `application/octet-stream`
  or `application/gltf-buffer` will fall back to trying both PNG and JPEG
  loaders.

Fully fixes #33796 (and fixes up #42501).

glTF: Fix parsing buffer data with application/gltf-buffer and image/* MIME types
See https://github.com/KhronosGroup/glTF/issues/944 for context on the
application/gltf-buffer MIME type.

The glTF 2.0 spec supports `image/jpeg` and `image/png` which can also be
base64-encoded in buffer URIs.

Fixes #33796.

7bf9787921 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

5f5ef98832 glTF: Fix tangent generation for non-blend shapes
PR #30877 was bogus as it made a blend shape-specific code block apply
to everything but blend shapes (as it seemed not to work properly *for*
blend shapes).

The proper fix should thus be to simply remove the problematic
block (and thus cleanup unnecessary logic).

Fixes #32712.
