  Log Message:
  -----------
  Reapply "[AMDGPU] fold `memref.subview/expand_shape/collapse_shape`  into `amdgpu.gather_to_lds`" (#150334)

This is a reapply of patch #149851. The reapply also fixes a CMake/Bazel
build issue, which was the reason of the revert. (Thanks @rupprecht )

Original patch (#149851) message:
-----
This PR adds a new optimization pass to fold
`memref.subview/expand_shape/collapse_shape` ops into consumer
`amdgpu.gather_to_lds` operations.
* Implements a new pass `AmdgpuFoldMemRefOpsPass` with pattern
`FoldMemRefOpsIntoGatherToLDSOp`
* Adds corresponding folding tests
