  [mlir][AMDGPU] Fix raw buffer ptr ops lowering (#122293)

This patch fixes several bugs in the lowering of AMDGPU raw buffer
operations. These bugs include:
- Incorrectly handling the offset of the memref, causing errors when
using subviews.
- Using the MaximumOp (float specific op) to calculate the number of
records.
 - The number of records in the static shape case.
 - The lowering when index bitwidth=i64.

Furthermore this patch also switches to use MLIR's data layout to get
the type size.
