[AMDGPU] fold `memref.subview/expand_shape/collapse_shape` into `amdgpu.gather_to_lds` (#149851)

`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
