  -----------
  [SystemZ][XRay] Reland XRay runtime support for SystemZ (#124611)

Adds the runtime support routines for XRay on SystemZ. Only function
entry/exit is implemented.

The original PR 113252 was reverted due to errors caused by adding DSO
support to XRay.
This PR is the original implementation with the changed function
signatures. I'll add an implementation with DSO support later.
