vppinfra: refactor test_and_set spinlocks to use clib_spinlock_t
Spinlock performance improved when implemented with compare_and_exchange instead of test_and_set. All instances of test_and_set locks were refactored to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize between processes rather than threads, so they cannot directly use clib_spinlock_t.
