Linux only. Support native (OS-wide) profiling for Raptor tests in CI
and locally using the perf profiler.

perf profiles the entire Browsertime instance that the test is run in.
The resulting profile is symbolicated with build symbols using Samply
and converted into a JSON profile in the Firefox Profiler format.

--perf-profile is introduced as a Raptor option and a Mozharness extra
option. A CI job with perf profiling can be created by adding
--perf-profile to the job's configuration. The job should be run with
./mach try 's --native-profiling flag.

To run a Raptor test locally with perf profiling, use the --perf-profile
flag with ./mach raptor

Attachment: Bug 2047451 - Add transform and Autoland tasks for Speedometer 3 native profiling on Linux. r?#perftest

These transforms configure perf profiling and symbolication dependencies
for Speedometer 3 Linux CI tasks when --native-profiling is used or
when running on Autoland.
