  [SystemZ][z/OS] Extend systemz-features.cpp and zvector.c with z/OS RUN lines (#224733)

Add `s390x-ibm-zos` RUN lines to
`clang/test/Driver/systemz-features.cpp`
covering the default, `-mhtm`/`-mno-htm`, and `-mvx`/`-mno-vx` cases.
The `-mvx` z/OS lines require `-march=arch11` because the default z/OS
CPU (zEC12) pre-dates vector support.

Add a second RUN in `clang/test/Sema/zvector.c` using triple
`s390x-ibm-zos` with `-target-cpu z13` so the file is exercised under
the z/OS code path.

These test extensions were carved out from
https://github.com/llvm/llvm-project/pull/223026 per reviewer request
(@uweigand): the extra test runs are good additions but are not related
to the i128 XPLINK64 change.
