MDEV-16264 fixup: Remove unused code and data

LATCH_ID_OS_AIO_READ_MUTEX,
LATCH_ID_OS_AIO_WRITE_MUTEX,
LATCH_ID_OS_AIO_LOG_MUTEX,
LATCH_ID_OS_AIO_IBUF_MUTEX,
LATCH_ID_OS_AIO_SYNC_MUTEX: Remove. The tpool is not instrumented.

lock_set_timeout_event(): Remove.

srv_sys_mutex_key, srv_sys_t::mutex, SYNC_THREADS: Remove.

srv_slot_t::suspended: Remove. We only ever assigned this data member
true, so it is redundant.

ib_wqueue_wait(), ib_wqueue_timedwait(): Remove.

os_thread_join(): Remove.

os_thread_create(), os_thread_exit(): Remove redundant parameters.

These were missed in commit 5e62b6a5e06eb02cbde1e34e95e26f42d87fce02.
