rts: Tracing support for nonmoving collection events
This introduces a few events to mark key points in the nonmoving garbage collection cycle. These include: * `EVENT_CONC_MARK_BEGIN`, denoting the beginning of a round of marking. This may happen more than once in a single major collection since we the major collector iterates until it hits a fixed point. * `EVENT_CONC_MARK_END`, denoting the end of a round of marking. * `EVENT_CONC_SYNC_BEGIN`, denoting the beginning of the post-mark synchronization phase * `EVENT_CONC_UPD_REM_SET_FLUSH`, indicating that a capability has flushed its update remembered set. * `EVENT_CONC_SYNC_END`, denoting that all mutators have flushed their update remembered sets. * `EVENT_CONC_SWEEP_BEGIN`, denoting the beginning of the sweep portion of the major collection. * `EVENT_CONC_SWEEP_END`, denoting the end of the sweep portion of the major collection.
