threads: during abrupt thread-exit, cleanup anyways (#48223)

Closes #47590 (pthread_cancel still forbidden though, since async mode
will corrupt or deadlock the process, and synchronously tested with
cancelation disabled whenever this is a lock is just a slow
implementation of a boolean)

Refs #47201 (only deals with thread exit, not other case where this is
an issue, like cfunction exit and gc-safe-leave)

May help #46537, by blocking jl_wake_libuv before uv_library_shutdown,
and other tweaks to GC mode. For example, avoiding:
