ngtsc has an internal performance tracing package, which previously has not really seen much use. It used to track performance statistics on a very granular basis (microseconds per actual class analysis, for example). This had two problems: * it produced voluminous amounts of data, complicating the analysis of such results and providing dubious value. * it added nontrivial overhead to compilation when used (which also affected the very performance of the operations being measured). This commit replaces the old system with a streamlined performance tracing setup which is lightweight and designed to be always-on. The new system tracks 3 metrics: * time taken by various phases and operations within the compiler * events (counters) which measure the shape and size of the compilation * memory usage measured at various points of the compilation process If the compiler option `tracePerformance` is set, the compiler will serialize these metrics to a JSON file at that location after compilation is complete.
