This diff looks busy, but the only actual change is the addition of colorama to
the list; everything else is just formatting changes that the pip-compile tool
generated for me.

More exactly: Instead of trying to compensate for only the previous sleep over/undershoot, we now try to keep each sampling loop to a schedule based on the very beginning of sampling, by adding the requested interval to the scheduled sampling time.
In addition, the sleep time is always kept to a minimum, to avoid making the system busier by having one loop right after the other -- also, this very-close data may be less useful.
And in presumably very busy times, one sleep and the following sampling work may take much more time than the requested sampling interval, trying to keep to schedule is now futile (it would require trying to effectively multiply the sampling rate, which seems unlikely to succeed, and would impact Firefox even more), in which case we revert to the full sampling interval.

This patch rewrites some parts of the GeckoProfiler code to make it clearer and easier to maintain. It also changes how the profiles get organized into separate folders for each type. Furthermore, the archives no longer have the full directory path in them. To do this, we also have to update browsertime.

mPostMeasurementTimeStamp records the time right after CPU measurements (point-based or interval) ended.
It is then used as the main sample timestamp, to both avoid another TimeStamp::Now() call, and to keep measurements and timestamp as close together as possible (and even closer in the next patch).

This handles the conversion (from TimeStamp to number of milliseconds since process start) once and gives it to subroutines.
It will also help in a following patch where this value will be more closely tied with the CPU usage value, so we need to make sure the sample timestamp is taken at a single point and then forwarded wherever it's needed, be it a duplicate or a real sample.
While here, the nested `delta` variables in the Sampler have been disambiguated for better clarity:
- `sampleStartDeltaMs` is at the start of each sampling loop,
- `threadSampleDeltaMs` is associated to one thread being sampled during that loop.

Now that we use an external dump_syms, we don't need to build
breakpad's.
This means we also don't need the dump_syms_rust_demangle crate anymore.

This patch converts `GeckoChildProcessServices.java` into a jinja template.
We also add an overlay generated from a jinja template for `AndroidManifest.xml`
that provides the definitions for content process services.
Note that even though Gradle supports simple substitution of variables in
manifests, I opted not to use that functionality. Since we need the more
powerful template functionality that jinja provides, I felt that having multiple
ways to substitute information into the manifest would be confusing, so we're
using jinja exclusively.

pylint_requirements.txt fail to install with the new pip resolver due
to a conflict between astroid and lazy-object-proxy.
Rather than bumping those packages and handling the potential fallout,
the package-upgrade has been deferred and we will use the legacy
resolver in the interrim.

In addition to the usual dot-release type of fixes, this also lets us drop a good amount of code that we had patched into our clang 11.

The `RunningTimes` class stores CPU measurements. It may seem overkill for only one value, but in the future more measurements will be added.
During sampling, CPU measurements are collected by platform-specific code. This patch doesn't produce anything yet, see later patches.
These are stored with the samples.
Note that for duplicated samples (when a thread is known to be "asleep"), we still need to collect new measurements, because there could potentially be some activity happening, e.g. in system calls.
Finally the measurements are output as extra "samples" values.
Units for these values may platform-specific, so they are stored in the top-level JSON "meta" object.
We don't collect running times in the Base Profiler (yet), but we still need to add the appropriate field names in the samples' "schema", as expected by profiler.firefox.com.

This patch adds "CPU Utilization" ("cpu" for short) as a new feature that will control the upcoming still-experimental CPU measurements.
Differential Revision: https://phabricator.services.mozilla.com/D99054
Instead of only capturing one feature (NoStackSampling), the sampler thread now stores all features so that any feature can be quickly looked at during sampling.
Currently this is still limited to NoStackSampling, a later patch will start using another feature.

We need it from both FormAutofillHeuristics and CreditCardRuleset, and it would make a circular import otherwise: FormAutofillHeuristics -> CreditCardRuleset -> FormAutofillHeuristics.
