As a basic check that the SVE signal frame is being set up correctly
verify that the vector length in the signal frame is the vector length
that the process has.

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.
