Summary:
Release notes: Introducting new option --invariantLevel NUMBER and dropping --omitInvariants
The new default is invariant level 0, which corresponds to the old --omitInvariants.
Level 1 is roughly what we used to do: Check invariants on (derived) abstract values.
Level 2 implements #1180: Checking that all accesses to built-ins do what Prepack expects them to do, including checks for when properties on built-ins are absent.
Level 3 adds checks for internal consistency, basically an internal debug level.
The serializer tests now run with the highest invariant level by default. The added invariants found a few issues that got addressed, including:
- Prepack exposes a TypedArray prototype, which is not a real thing. It's now marked as `__refuseSerialization`, and no invariants are emitted for such things.
- Global variables / properties on the global object are special. Those are not yet handled at level 2.
- Accesses to Prepack magic functions that generally start with `__` should not produce invariant checks.
- Magic code generation for loops should not take into account objects that are `__refuseSerialization`.
- All invariant statements get a unique id to make it easier to locate them.
- I marked some test cases which depend on counting occurrences in the output as "// omit invariants", as the additional invariants increased some such counts.
As part of testing, I also found it necessary to make the --invariantMode more useful; it now also allows specifying nativeLoggingHook which is the preferred way of logging in React Native.
To reduce the number of checks by a few orders of magnitude in practice, each property is only checked on first access. This is tracked by a global variable `__checkedBindings`.
This pull requests incorporates all aspects of the #1709 (which I abandoned).

Summary:
Release notes: adds "node-react" compatibility mode
Adds the "node-react" compatibility mode, which is like "fb-www", but doesn't contain the internal FB mocks. This mode is ideal for library authors who might want to experiment with the features of the React compiler in an environment that has basic React/Relay mocks as well as `require` and `module.exports` partial support.
I'll be adding relevant documentation for this on the wiki too.

Summary:
This addresses the issue https://github.com/facebook/prepack/issues/1282 although the issue also requests for --additionalFunctions option which is not part of this commit. User should now be able to see --lazyObjectsRuntime option in the options list on https://prepack.io/repl.html. Ideally this should be an enum but this will accept a freeform string in this revision.

Release notes: adds option to parse and strip Flow annotations
In a [tweet I made at the end of last year](https://twitter.com/trueadm/status/944908776896978946) I linked to a REPL example that contained Flow type annotations. The example is now broken as we removed Flow type annotation parsing. :(
This PR adds this back behind the option `stripFlow` which is now enabled by default on the REPL and for React tests. I've also added a test to match the REPL for regression checking so this doesn't happen.

Release Note: Fix duplicate edges issue in Prepack heap visualization.
This PR did two things:
1. Fix duplicate edges issue in Prepack heap visualization by using unique identifier for edge id field.(#1300)
2. Prepack heap visualization supports two formats: 1. Dot language formatted used by CLI. 2. JSON format used by Vis.js library to visualize in website REPL. This PR allows both.

Issue https://github.com/facebook/prepack/issues/1296.
The previous version of Tether Select that was used in the website had `z-index: 100;` (still can check it in `gh-pages` branch) but in the version that we use from CDN, in order to reduce the size of Prepack repo, there is no `z-index`. So I've added it to the website styles.

Summary:
Release note: none
To address issue #956 .
The idea is to have all documentation (aka "the website") in a single `docs/` directory on the `master` branch like [Jest](https://github.com/facebook/jest/tree/master/docs) and [Relay](https://github.com/facebook/relay/tree/master/docs) do. This directory then serves as a single source of truth to publish the `gh-pages` branch.
This PR:
- Moves the current content of the `gh-pages` branch to a `docs/` directory in `master`
- Provides a bash script for maintainers to easily publish the `gh-pages` branch from the `docs/` directory. The script also builds `prepack.min.js` from master to make sure gh-pages always has the latest version of prepack.
Additionally, I noticed the `gh-pages` branch had two `prepack.min.js` files (one in `./` and one in `./js/`). I removed the first one because it is apparently not used but it may break other websites if they references that file.
0. Fork the repo to avoid modifying the real website
1. Change the site
`> git checkout master`
`> echo ".nav { background-color: chartreuse; }" >> docs/css/style.css`
`> git add docs/css/style.css`
`> commit -m "The navigation bar looks better in green"`
`> git push`
2. Run the publication script:
`> ./scripts/publish-gh-pages.sh`
3. Verify that the gh-pages has been updated:
`> git checkout gh-pages`
`> git pull`
`> git diff HEAD~ # should show the line you added`
