958ede1ed9 astc_decoder: Optimize the use EncodingData 
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.

79621cca95 astc_decoder.comp: Remove unnecessary LUT SSBOs

fe7d3006f5 astc: Various robustness enhancements for the gpu decoder 
These changes should help in reducing crashes/drivers panics that may
occur due to synchronization issues between the shader completion and
later access of the decoded texture.

13b046aae1 astc_decoder: Fix LDR CEM1 endpoint calculation 
Per the spec, L1 is clamped to the value 0xff if it is greater than 0xff. An oversight caused us to take the maximum of L1 and 0xff, rather than the minimum.

Huge thanks to wwylele for finding this.

e5da434498 textures: Reintroduce CPU ASTC decoder 
Users may want to fall back to the CPU ASTC texture decoder due to hangs
and crashes that may be caused by keeping the GPU under compute heavy
loads for extended periods of time. This is especially the case in games
such as Astral Chain which make extensive use of ASTC textures.

c0c51e4be0 astc: Increase integer encoded vector size 
Invalid ASTC textures seem to write more bytes here, increase
the size to something that can't make us push out of bounds.

185c16d893 astc: Return zero on out of bound bits 
Avoid out of bound reads on invalid ASTC textures.
Games can bind invalid textures that make us read or write out of bounds.

d25b097e84 video_core: Rewrite the texture cache 
The current texture cache has several points that hurt maintainability
and performance. It's easy to break unrelated parts of the cache
when doing minor changes. The cache can easily forget valuable
information about the cached textures by CPU writes or simply by its
normal usage.The current texture cache has several points that hurt

This commit aims to address those issues.
