Alex Rickabaugh aaa16f286d feat(ivy): performance trace mechanism for ngtsc (#29380)
This commit adds a `tracePerformance` option for tsconfig.json. When
specified, it causes a JSON file with timing information from the ngtsc
compiler to be emitted at the specified path.

This tracing system is used to instrument the analysis/emit phases of
compilation, and will be useful in debugging future integration work with
@angular/cli.

See ngtsc/perf/README.md for more details.
