[syscalls][vmo][op_range] add rights checking for different ops

Test for the WRITE right for most of the ops, except the simple cache
clean ops which cant modify data and thus only need read. This mirrors
what arm64 already enforces for user vs supervisor permissions of the
different cache ops. All but a pure invalidate is a read operation,
permission wise.
