c57be069 - Move population of common MetricsContext fields to record_compilation_metrics (#141291)

Move population of common MetricsContext fields to record_compilation_metrics (#141291) Summary: Fix outstanding TODOs related to logging of CompilationMetrics by moving the population of common fields to record_compilation_metrics() instead of populating those independently wherever we use a the metrics_context contextmanager: * Keep track of start and end time in MetricsContext and pass those to record_compilation_metrics() and populate those fields in that function. * Pass exception info to record_compilation_metrics() and populate those field in that function. * Add a new contextmanager, chromium_event_timed, to create the start/end "dynamo" event. This is important because I want this contextmanager to complete _after_ building the CompilationMetrics. * Populate the compile_id field centrally in record_compilation_metrics(). * Populate the structured_logging_overhead centrally in record_compilation_metrics(). * Add the CompilationMetrics to the current chromium event in record_compilation_metrics(), after all common fields have been added. In a future diff, I can also add _all_ compilation metrics to the chromium event.
