riscv: selftests: Add signal handling vector tests

Browse source

Add two tests to check vector save/restore when a signal is received
during a vector routine. One test ensures that a value is not clobbered
during signal handling. The other verifies that vector registers
modified in the signal handler are properly reflected when the signal
handling is complete.
