Add some arm64/signal specific boilerplate and utility code to help further testcases' development.
Introduce also one simple testcase mangle_pstate_invalid_compat_toggle and some related helpers: it is a simple mangle testcase which messes with the ucontext_t from within the signal handler, trying to toggle PSTATE state bits to switch the system between 32bit/64bit execution state. Expects SIGSEGV on test PASS.

Does anything in the series still use SSBS_SYSREG?
If not, please drop it. No need to remove my Reviewed-by just for thato change.
