  [MLIR][Affine] Fix memref replacement in affine-data-copy-generate (#139016)

Fixes: https://github.com/llvm/llvm-project/issues/130257

Fix affine-data-copy-generate in certain cases that involved users in
multiple blocks. Perform the memref replacement correctly during copy
generation.

Improve/clean up memref affine use replacement API. Instead of
supporting dominance and post dominance filters (which aren't adequate
in most cases) and computing dominance info expensively each time in
RAMUW, provide a user filter callback, i.e., force users to compute
dominance if needed.
