Adds comprehensive support for ETC2 compressed texture formats (ETC2_RGB,
ETC2_RGBA, ETC2_RGB_PTA) in both UNORM and SRGB variants. This addresses
rendering issues in games like Hogwarts Legacy that use these formats.
Changes:
- Add ETC2 texture format enums (TextureFormat::ETC2_RGB_SRGB,
ETC2_RGBA_SRGB) and component types (SNORM_FORCE_FP16, UNORM_FORCE_FP16)
- Implement format lookup mappings for all ETC2 variants in
format_lookup_table.cpp
- Add PixelFormat enum values and block size tables for ETC2 formats
- Integrate ETC2 support into Vulkan backend with proper VkFormat mappings
- Add IsOptimalEtc2Supported() device capability check
- Update texture cache to handle ETC2 format conversion when needed
- Add ETC2 format cases to PixelFormat formatter for logging
- Improve shader environment texture handle validation with graceful
fallback for invalid handles
Fixes assertion failures for texture formats 90 and 99, enabling proper
rendering of ETC2 compressed textures using native Vulkan support.

We can iterate through the AdvancedGraphics settings and generate the UI
during runtime. This doesn't help runtime efficiency, but it helps a ton
in reducing the amount of work a developer needs in order to add a new
setting.
Visual Studio has an option to search all files in a solution, so I
did a search in there for "default:" looking for any missing break
statements.
I've left out default statements that return something, and that throw
something, even if via ThrowInvalidType. UNREACHABLE leads towards throw
R_THROW macro leads towards a return
Given the issues with GPU accelerated ASTC decoding with NVIDIA's latest drivers, parallelize astc decoding on the CPU.
Uses half the available threads in the system for astc decoding.

Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.
This buffer was a list of EncodingData structures sorted by their bit length, with some duplication from the cpu decoder implementation.
We can take advantage of its sorted property to optimize its usage in the shader.
Thanks to wwylele for the optimization idea.
