Function glean::rlb_flush_dispatcher

#[no_mangle]pub extern "C" fn rlb_flush_dispatcher()

Unblock the global dispatcher to start processing queued tasks.

This should only be called if it is guaranteed that initialize will never be called.

Note: Exported as a FFI function to be used by other language bindings (e.g. Kotlin/Swift) to unblock the RLB-internal dispatcher. This allows the usage of both the RLB and other language bindings (e.g. Kotlin/Swift) within the same application.
