clayjohn f84c6df8d1 Use DXT1 when compressing PNGs with RGB format
This results in much smaller file sizes with the same quality

Juan Linietsky 28f51ba547 Refactor high quality texture import
* Only two texture import modes for low/high quality now:
  * S3TC/BPTC
  * ETC2/ASTC
* Makes sense given this is the general preferred and most compatible combination in most platforms.
* Removed lossy_quality from VRAM texture compression options. It was unused everywhere.
* Added a new "high_quality" option to texture import. When enabled, it uses BPTC/ASTC (BC7/ASTC4x4) instead of S3TC/ETC2 (DXT1-5/ETC2,ETCA).
* Changed MacOS export settings so required texture formats depend on the architecture selected.

This solves the following problems:

* Makes it simpler to import textures as high quality, without having to worry about the specific format used.
* As the editor can now run on platforms such as web, Mac OS with Apple Silicion and Android, it should no longer be assumed that S3TC/BPTC is available by default for it.

rsjtdrjgfuzkfg a1a2c2c2ce etcpak: Fix ETCPAK_TYPE_ETC2_RA_AS_RG
This commit fixes texture compression via ETCPAK_TYPE_ETC2_RA_AS_RG,
switching to the right color channels and using the right compression
method. Textures imported with previous versions need to be re-imported
in order to render correctly.

One Copyright Update to rule them all
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

etcpak: Update to upstream commit 7c3cb6f (Jul 29, 2021)
Adds a new `useHeuristics` compression mode for ETC2.
Upstream defaults to enable it so we do the same.

Import: Cleanup and optimize etcpak compression method
Avoid unnecessary allocation of temporary buffers for each mip, and creates
only one Image with the compressed data.
Also renames variable and reorders code for clarity.

Clarify that squish is now only used for decompression.

Documented which formats can be decompressed in Image.
