kselftest/arm64: Add streaming SVE to SVE ptrace tests
In order to allow ptrace of streaming mode SVE registers we have added a
new regset for streaming mode which in isolation offers the same ABI as
regular SVE with a different vector type. Add this to the array of regsets
we handle, together with additional tests for the interoperation of the
two regsets.
