bazel: add --starlark_cpu_profile=<file> flag

And an integration test.

RELNOTES:
The --starlark_cpu_profile=<file> flag writes a profile in
pprof format containing a statistical summary of CPU usage
by all Starlark execution during the bazel command. Use it
to identify slow Starlark functions in loading and analysis.
