[roll third_party/pigweed] pw_build: Add --write-trace option to pw-wrap-ninja
This commit adds a new option to pw-wrap-ninja to write a trace file for
the build, in the Chromium trace_event format. This trace can be opened
with the Perfetto UI.
This trace only includes timing information from the build, not
dependency information from Ninja or additional compiler output. Thus,
it is simpler than a more comprehensive tool such as Fuchsia's
"ninjatrace". However, it's simple to use and still provides value.
Tested:
Built Pigweed with pw-wrap-ninja and the --write-trace option.
Confirmed the trace was viewable with the Perfetto UI.
