tu: Trivially implement VK_EXT_texel_buffer_alignment 

The previous alignment of 64 bytes, which we got from the blob,
indicates that single-texel alignment isn't supported. So just do a
trivial no-op implementation that returns the same alignment as before.
This matches what newer blobs that expose this extension do.
