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.

A signal frame with SVE may validly either be a bare struct sve_context or
a struct sve_context followed by vector length dependent register data.
Support either in the generic helpers for the signal tests, and while we're
at it validate the SVE vector length reported.

Allow testcases for SVE signal handling to flag the dependency and be
skipped on systems without SVE support.

The PAC tests check to see if the system supports the relevant PAC features
but instead of skipping the tests if they can't be executed they fail the
tests which makes things look like they're not working when they are.

When skipping the tests due to a lack of system support for MTE we
currently print a message saying FAIL which makes it look like the test
failed even though the test did actually report KSFT_SKIP, creating some
confusion. Change the error message to say SKIP instead so things are
clearer.
