Translator: Fix index-checks vs comma ↗

摘要待补：In `expression[index]`, when checking if certain limitations apply to the `expression` and `index`, skip all comma operator left-hand sides in `expression` before checking the qualifier. If for example `gl_SomeBuiltIn[index]` has a restriction, so does `(x, gl_SomeBuiltIn)[index]`.

Vulkan: Map only remaining buffer size in getIndexRange ↗

摘要待补：Correct the mapped buffer range length in getIndexRange to only map the remaining buffer size. This prevents staging buffer copies from reading past the end of the suballocation.

Optimize robust init check during GenerateMipmap ↗

摘要待补：Add an enum class EnsureInitializedLevels to optionally skip robust initialization for texture levels above the base level during glGenerateMipmap since they will be overwritten.

GL: Use PixelPack/Unpack structs in ContextStateGL ↗

摘要待补：Instead of enumerating the members, store them in the frontend structs. This matches the single dirty bit which represents all of them together.

Vulkan: Remove TextureVk::getImageViews() ↗
