  [AMDGPU][GlobalISel] Pre-commit tests for readanylane merge regbank combine (NFC) (#214355)

Add regbank-combiner tests covering a copy to vgpr whose source is a
merge or
build_vector of `G_AMDGPU_READANYLANE` results mixed with uniform
values.

These currently keep the round trip through sgprs. The tests also cover
the two
cases where the transform must not fire:

- the sgpr merge has another user, so it has to be kept;
- all merge sources are uniform, so moving the copy to the sources would
not
  remove any readanylane.

Pre-commit only, no functional change. The combine that removes the
round trip
is in the stacked PR.
