  [mlir][vector] Refine Vector to LLVM lowering options (#159553)

This is a follow-up to https://github.com/llvm/llvm-project/pull/144307,
where we removed `vector.matrix_multiply` and `vector.flat_transpose`
from the Vector dialect.

This PR:
* Updates comments that were missed in the previous change.
* Renames relevant `-convert-vector-to-llvm=` options:
  - `vector-contract-lowering=matmul` → `vector-contract-lowering=llvmintr`
  - `vector-transpose-lowering=flat_transpose` → `vector-transpose-lowering=llvmintr`

These new names better reflect the actual transformation target - LLVM
intrinsics - rather than the now-removed abstract operations.
