When isBuffer=true the array allocates _bufferTextureRefs and leaves
_textureRefs null. SetSamplers and QueueWriteToReadBarriers dereferenced
_textureRefs unconditionally, and the TextureView branch of SetTextures
and SetImages did the same when a non-buffer view landed in a
buffer-targeted array. Reached in practice when shaders sample from
texel-buffer-typed array bindings with mixed contents.
Branch SetTextures and SetImages on _isBuffer first, then on input type.
A TextureView in a buffer-mode array, and a TextureBuffer in a
non-buffer-mode array, are both dropped to null. The latter was a
pre-existing mirror bug, unreached by current callers.
Early-return from SetSamplers and QueueWriteToReadBarriers for
buffer-mode arrays: texel-buffer descriptors carry no sampler state and
storage barriers do not apply.
