I didn't enable this by default for clang due to making the build time 10% worse or so. Unfortunate, but tbh devs for whom 10% of build time is not *that* bad should probably simply enable this. Change-Id: I8d1e5b6f3f76c649a4e2f115f534f7f97cee46e6

We now have Clang build profiling available, which generates Chrome
tracing files for each compilation unit. To enable it, run meson configure build -Dprofile-build=enabled then rerun the compilation.
If you want to make the build go faster, do a clang build with meson, then run
maintainers/buildtime_report.sh build, then contemplate how to improve the
build time.
You can also look at individual object files' traces in https://ui.perfetto.dev.
