gdb_is_target_native uses "maint print target-stack", which is unnecessary when checking whether gdb_protocol is empty would do. Checking gdb_protocol is more efficient, and can be done before starting GDB and running to main, unlike gdb_is_target_native. This adds a new gdb_protocol_is_native procedure, and uses it in place of gdb_is_target_native. At first, I thought that we'd end up with a few testcases needing to use gdb_is_target_native still, especially multi-target tests that connect to targets different from the default board target, but no, actually all uses of gdb_is_target_native could be converted. gdb_is_target_native will be eliminated in a following patch. In some spots, we no longer need to defer the check until after starting GDB, so the patch adjusts accordingly.
