  [AMDGPU] Lay groundwork for stridemark type / addrspace(9) via sgep (#198930)

This commit introduces and documents the `amdgpu.stridemark` target
type, which is used to express when a structured.gep intrinsic is being
used to increment/decrement the index part of a `ptr addrspace(9)` (as
opposed to GEP, which manipulates the offset part)

Future PRs will add inbounds/nusw/nuw support to structured GEP to
enable more efficient code generation and then will implement a lowering
of these structured GEPs to struct.buffer intrinsics.
