[shader_recompiler] handle dynamic texture descriptor strides (#3898)

this fixes dynamic texture descriptors that are not laid out as simple 8-byte entries

tested on steam deck/amd

notes
- DynamicDescriptorSizeShift called twice because i moved it away from the struct but doing it this way keeps the patch just in this single file than adding a new derived field in the shared struct (i also think its just a cheap recomputation anyways)
- removed cbuf scanning because i figured out how to do a bounds check statically
