[LOCAL] Remove stale frame event code from PerformanceTracer

The cherry-pick of early commits (ce60f27, 85905ad) introduced
frame event types and methods to PerformanceTracer that were
subsequently removed on main as part of the backout/re-land cycle. Since
we skipped the backout commits (the originals weren't on the branch),
these stale references remained.

Frame timing is now handled entirely through HostTarget and
TraceEventGenerator, so these PerformanceTracer methods and visitor
lambdas are dead code that fails to compile.
