Summary:
Several changes here. The `Text.md` and `PixelRatio.md` files were appended to the autodocs during site generation. This seemed excessive for just two files, so I've just merged the content into the autodocs themselves. It should help us simplify the website generation process in the future.
I've also merged IssueGuidelines.md and PullRequestGuidelines.md into the Contribution/Maintainers guidelines to improve their visibility.
Finally, I renamed Help to Community in the nav bar.
Ran the website locally, and verified every page rendered as expected: the Community page, Contributing page, Maintainers page.

Summary:
Importing `react` modules from `react-native` has been deprecated since 0.25 so I think it's safe to remove it now since everyone has migrated their code and it is now well know and documented that you import from different packages. This finishes the spring cleanup of `react-native-implementation.js` :)
**Test plan**
Tested that UIExplorer still works.

Summary:
If tracking is enabled and the sampling check passes on a scroll or layout event,
we compare the scroll offset to the layout of the rendered items. If the items don't cover
the visible area of the list, we fire an `onFillRateExceeded` call with relevant stats for
logging the event through an analytics pipeline.
The measurement methodology is a little jank because everything is async, but it seems directionally
useful for getting ballpark numbers, catching regressions, and tracking improvements.
Benchmark testing shows a ~2014 MotoX starts hitting the fill rate limit at about 2500 px / sec,
which is pretty fast scrolling.
This also reworks our frame rate stuff so we can use a shared `SceneTracking` thing and track blankness
globally.

Summary:
The `UIManager` already has a lot of responsibilities and is deeply
tied with React Native's view architecture. This diff separates out a
`DeviceInfo` native module to provide information about screen dimensions and
font scale, etc.

Summary: This adds an alternative logging method that can be called from native side. `logIfNoLoggingHook()` will pass the message to console only if there's Chrome debugger attached. This new method sends the message to console regardless to notify the developers better.

Summary:
Enable back navigation on Apple TV (with the remote's menu button) in code making use of BackAndroid. The module is renamed to BackHandler. BackAndroid is still exported to ReactNative for now, until external projects switch to using the new name for the module. The navigation in https://github.com/react-community/react-navigation makes use of this module.
**Test plan**: Manual testing with an example app (https://github.com/dlowder-salesforce/react-nav-example).

Summary:
The PR description has been updated to reflect the new approach.
**Breaking Change Summary**
On Android, the following properties now return a different number:
- `Dimensions.get('window').fontScale`
- `Dimensions.get('screen').fontScale`
- `PixelRatio.getFontScale()`
This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.
These properties used to return a value representing font scale times density ([`DisplayMetrics.scaledDensity`](https://developer.android.com/reference/android/util/DisplayMetrics.html#scaledDensity)). Now they return a value representing just font scale ([`Configuration.fontScale`](https://developer.android.com/reference/android/content/res/Configuration.html#fontScale)).
**PR Description**
This PR changes a few things:
- Correctly exposes the font scale to JavaScript as `Dimensions.get('screen').fontScale`. UIManager was exporting `DisplayMetrics.scaledDensity` under the name `fontScale`. How

Summary:
On Android with dev mode on, we're seeing a regular SIGSEGV when pushing a lot of animation declarations over the bridge. We tracked this down to being not specific to animations, but the crash is caused in `deepFreezeAndThrowOnMutationInDev`.
Specifically: the provided object to freeze is modified while looping, replacing the current key access to a getter/setter. After the modification, JSC crashes during retrieval of the next key - but only when there are a lot of events passing over the bridge.
We have a hunch that this is due to a bug in JSC object enumeration but did we not look into it further yet. Any help here is welcome. The JS code seems all right at first sight and shouldn't cause a segmentation crash.
The workaround in this PR is to retrieve the keys first from the object and then looping over that array. In our app and in a reduced app test case this fixes the crash.
If needed I can provide the reduced app test case. It's really tricky to make a test for this as it requires to be run
