  [SystemZ] Implement .machine (push|pop) directives (#137302)

The `.machine push` and `.machine pop` directives were missing from the
SystemZ Backend Asm Parser. This PR adds them, and expands the
corresponding test to test proper operation.

Internally, this is modeled as a simple stack implemented on a
`SmallVector<StringRef>`.
