Salieri: Detect and avoid caching shaders using bindless textures (#2097)

Browse source 
* Salieri: Add blacklist system and blacklist shaders using bindless

Currently the shader cache doesn't have the right format to support
bindless textures correctly and may cache shaders that it cannot rebuild
after host invalidation.

This PR address the issue by blacklisting shaders using bindless
textures.

THis also support detection of already cached broken shader and handle removal
of those.

* Move to a feature flags design to avoid intrusive changes in the translator

This remove the auto correct behaviour

* Reduce diff on TranslationFlags

* Reduce comma on last entry of TranslationFlags

* Fix inverted logic and remove leftovers

* remove debug edits oops
