[RESTRICT AUTOMERGE] Remove libsync usages

libsync depends on <debugfs>/sync/sw_sync to create the sync timeline.
However, because debugfs is not available on the production build,
libsync must be used only for a debugging.

This change therefore removes libsync usages from EVS manager's frame
delivery mechanism and rewrites the synchronization with a mutex and a
conditional variable.
