Support Chrome's about:traces export format

See original GitHub issue

STR: Load https://nparashuram.github.io/ChainReactApp2019/hermes/trace-hermes.json AR:

Error: "Unserializing the profile failed: TypeError: e.meta is undefined"
    $i process-profile.js:1149
    hl receive-profile.js:892

Tagging as feature, assuming there are a few differences between about:tracing and Chrome’s Performance DevTools format.

update: see https://github.com/firefox-devtools/profiler/issues/2166#issuecomment-519577522. This is a quite involved bug.

Worth noting that Chrome traces (which are also produced by the invaluable clang -ftime-trace) can be viewed via https://ui.perfetto.dev.
