kselftest/arm64: Add coverage for the ZA ptrace interface
Add some basic coverage for the ZA ptrace interface, including walking
through all the vector lengths supported in the system. Unlike SVE
doing syscalls does not discard the ZA state so when we set data in ZA
we run the child process briefly, having it add one to each byte in ZA
in order to validate that both the vector size and data are being read
and written as expected when the process runs.
