JFonS 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.

readability.
## bullet
- Upstream: https://github.com/bulletphysics/bullet3
- Version: 2.89 (830f0a9565b1829a07e21e2f16be2aa9966bd28c, 2019)
- License: zlib
Files extracted from upstream source:
- src/* apart from CMakeLists.txt and premake4.lua files
- LICENSE.txt
## certs
- Upstream: Mozilla, via https://apps.fedoraproject.org/packages/ca-certificates
- Version: 2018.2.26 (2018)
- License: MPL 2.0
File extracted from a recent Fedora install:
/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
(It can't be extracted directly from the package,
as it's generated on the user's system.)
## cvtt
- Upstream: https://github.com/elasota/cvtt
- Version: 1.0.0-beta4 (cc8472a04ba110fe999c686d07af40f7839051fd, 2018)
- License: MIT
Files extracted from upstream source:
- all .cpp, .h, and .txt files in ConvectionKernels/
## embree
- Upstream: https://github.com/embree/embree
- Version: 3.12.1 (69bd4c272f1ed608494f233ecfff3feec516880b, 2020)
- License: Apache 2.0
Files extracted from upstream:
- All cpp files listed in `modules/raytrace/godot_update_embree.py`
- All header files in the directories listed in `modules/raytrace/godot_update_embree.py`
Some minor changes have been made in order to fix build errors.
They are marked with `// -- GODOT start --` and `// -- GODOT end --`
comments. Apply the patches in the `patches/` folder when syncing on newer upstream
commits.
## enet
- Upstream: http://enet.bespin.org
- Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)
- License: MIT
Files extracted from upstream source:
- all .c files in the main directory (except unix.c win32.c)

Important: enet.h, host.c, protocol.c have been slightly modified
to be usable by Godot's socket implementation and allow IPv6 and DTLS.
Apply the patches in the `patches/` folder when syncing on newer upstream
commits.
Three files (godot.cpp, enet/godot.h, enet/godot_ext.h) have been added to provide
enet socket implementation using Godot classes.
It is still possible to build against a system wide ENet but doing so
will limit its functionality to IPv4 only.
