  [mlir][AMDGPU] Add folders for memref aliases to TDM base creation (#184567)

The TDM base creation (amdgpu.make_tdm_base and
amdgpu.make_gather_tdm_base) take references to a
`%memref[%i0, %i1,, ...]` for the starting point of the tiles in
global/shared memory that the TDM descriptor refers to. Memory alias ops
can be safely folded into these operations, since these two memref
operands are just pointers to a scalar starting pint and don't have
semantics that depend on the memref layout (except to the extent that it
defines a location in memory).

While I'm here, I've cleaned up a few things, like the incorrect file
header and fixed the tests to not use integer address spaces.
