Make deps/exprtk dependency optional

Guard the vendor event emission with obs_get_module("obs-websocket").
During obs_shutdown() modules are unloaded one-by-one; obs-websocket is
unloaded before advanced-scene-switcher, so the proc handler pointer (_ph)
cached in obs-websocket-api.h is already stale when FreeSceneSwitcher()
runs its stop steps. proc_handler_call() then dereferences freed memory
(use-after-free in pthread_mutex_unlock).

The existing OBSIsShuttingDown() guard does not catch this path: the
forced-exit that follows a "Source Cleanup Error" (scene collection
switch) never fires the SCRIPTING_SHUTDOWN frontend event, so the
plugin's obsIsShuttingDown flag is not set. obs_get_module() returns NULL
once the module is unloaded, which is the reliable signal that
obs-websocket's proc handler is gone.
