Summary:
While it would be better to be able to do all of the ownership metadata at the Buck macro level, that proved to be more work than expected.
This diff adds the corresponding pfh label to all targets in `xplat/js/react-native-github` that have a Supermodule label. Once the migration is complete the Supermodules labels will be able to be removed.

This Diff moves from specifying a list of files to use file(GLOB) with
CONFIGURE_DEPENDS on several CMakefiles.

Summary:
Rearranges folly_futures configuration into a static library only required for `hermes-inspector` + `folly_runtime` which merges `folly_json` and mutex-related implementations `folly_futures` was used for. As `hermes-executor-debug` is removed by `vmCleanup` configurations later, it allows to shave additional 300KB from the release APK size.

Summary:
This is the first round of CMake files to support the React Native build on Android.
They're supposed to eventually replace the various Android.mk files we have around in the codebase.
So far we're not actively using them. This is the first step towards migrating our
setup to use CMake

You can read more about this rule on https://clang.llvm.org/extra/clang-tidy/checks/modernize-pass-by-value.html
# Isn't it wasteful to copy? Isn't reference more efficient?
This rule of thumb is no longer true since C++11 with move semantics. Let's look at some examples.
# Option one
```
class TextHolder
{
public:
TextBox(std::string const &text) : text_(text) {}
private:
std::string text_;
};
```
By using reference here, we prevent the caller from using rvalue to and avoiding copy. Regardless of what the caller passes in, copy always happens.
# Option two
```
class TextHolder
{
public:
TextBox(std::string const &text) : text_(text) {}
TextBox(std::string &&text) : text_(std::move(text)) {}
private:
std::string text_;
};
```
Here, we provide two constructors, one for const reference and one for rvalue reference. This gives the caller option to avoid copy. But now we have two constructors, which is not ideal.
# Option three (what we do in this diff)
```
class TextHolder
{
public:
TextBox(std::string text) : text_(std::move(text)) {}
private:
std::string text_;
};
```
Here, the caller has option to avoid copy and we only have single constructor.

Summary:
We have `LOCAL_SHARED_LIBRARIES` that are getting longer and are
making reviewing them on Diffs quite hard.
Having all the list of the dependency on a single line is suboptimal
and it makes hard to find duplicated entries.
I've updated the longest `LOCAL_SHARED_LIBRARIES` to be multilines and
I've sorted the entries here.

Summary:
Add unit tests for Layout Animations.
This first batch generates a random mutation, then animates it to completion.
I found one issue with UPDATE+REMOVE+INSERT animation consistency. That shouldn't cause any crashes in production, but is a chance to improve consistency of mutations overall - and could in theory point to memory corruption, though it's somewhat unlikely.
I ran with randomized seeds, found issues, fixed them, re-ran to ensure issues were fixed, rinsed and repeated. At the end I was able to run dozens of times (with random seeds) and found nothing.
The next step is to repeatedly generate mutations that conflict with ongoing animations.

Change the `TransactionTelemetryTest` to use a mock clock or change the tests to only test if at least x amount of time has passed.
Using a mock clock is the only way to make the test deterministic and be able to assert on the sub-results of the captured phases.

Summary:
The `TransactionalTelemetryTest`s are flaky because they use a real clock and assert on how much time has passed (with a threshold, but that's no good either).
Using the real clock in the test is the cause for the test to be flaky because it depends on the assumption that it's the sole process running, never risking to be put in the process-queue of the OS. However, that's not the case and is why the test sporadically fails if the OS decided to schedule other threads/process in the middle of the test.
This diff allows parametrising the `TransactionTelemetry` class with the clock implementation so that tests can use a Mock Clock if desired (separate diff).

Summary:
The current test failures don't include the values passed to `EXPECT` which makes it difficult to understand if the test ended earlier or later then expected.
```
Failure: Value of: (commitDuration >= 1000 - threshold) && (commitDuration <= 1000 + threshold)
Actual: false
Expected: true
```
This diff uses the gtest `EXPECT_NEAR` to get exception messages including the delta:
```
Failure: The difference between telemetryDurationToMilliseconds(telemetry.getTextMeasureTime()) and 600 is 153, which exceeds threshold, where
telemetryDurationToMilliseconds(telemetry.getTextMeasureTime()) evaluates to 753,
600 evaluates to 600, and
threshold evaluates to 70.
```
This doesn't change the test's flakiness because of how sleep is implemented.
