deps: backport 9da3ab6 from V8 upstream
This patch exposes a new flag perf_basic_prof_only_functions (disabled by
default) that can be useful for the use-case of running always-on profiling on
long running production jobs.

New flag --perf_basic_prof_only_functions
Restricts linux perf-event code range reporting to functions only (i.e. on
stubs.) While this makes the gathered ticks less accurate, it reduces the
growth of the /tmp/perf-${pid}.map file.
