This migrates the compiler's bundler to esbuild instead of rollup.
Unlike React, our bundling use cases are far simpler since the majority
of our packages are meant to be run on node. Rollup was adding
considerable build time overhead whereas esbuild remains fast and has
all the functionality we need out of the box.

It turns out npm sets the latest tag by default so simply removing it
didn't change the previous behavior.
The `latest` tag is typically used for stable release versions, and
other tags for unstable versions such as prereleases. Since the compiler
is still in prerelease, let's set the latest tag only for
non-experimental releases to help signal which version is the safest to
try out.

> The `latest` tag is published by default if no tag is specified, which
> is what we had done since the first release of the compiler
In my last PR to auto publish compiler releases I had added the
experimental tag to be used in publishing. However because we had
already previously published to the latest tag (which is non-removable)
this means that the `latest` tag is pinned to an old version. That makes
untagged installs of the compiler default to that old version instead of
whatever is the latest.
This changes the behavior back to what it was before. Since we are still
in the experimental release of the compiler anyway it seems fine to use
the latest tag. When we reach stable, we can update this to only push to
latest for stable releases.

This PR updates to use SSA form through the entire compilation pipeline. This means that in both HIR form and ReactiveFunction form, `Identifier` instances map 1:1 to `IdentifierId` values. If two identifiers have the same IdentifierId, they are the same instance. What this means is that all our passes can use this more precise information to determine if two particular identifiers are not just the same variable, but the same SSA "version" of that variable.
However, some parts of our analysis really care about program variables as opposed to SSA versions, and were relying on LeaveSSA to reset identifiers such that all Identifier instances for a particular program variable would have the same IdentifierId (though not necessarily the same Identifier instance). With LeaveSSA removed, those analysis passes can now use DeclarationId instead to uniquely identify a program variable.
Note that this PR surfaces some opportunties to improve edge-cases around reassigned values being declared/reassigned/depended-upon across multiple scopes. Several passes could/should use IdentifierId to more precisely identify exactly which values are accessed - for example, a scope that reassigns `x` but doesn't use `x` prior to reassignment doesn't have to take a dependency on `x`. But today we take a dependnecy.
My approach for these cases was to add a "TODO LeaveSSA" comment with notes and the name of the fixture demonstrating the difference, but to intentionally preserve the existing behavior (generally, switching to use DeclarationId when IdentifierId would have been more precise).
Beyond updating passes to use DeclarationId instead of Identifier/IdentifierId, the other change here is to extract out the remaining necessary bits of LeaveSSA into a new pass that rewrites InstructionKind (const/let/reassign/etc) based on whether a value is actually const or has reassignments and should be let.

Publishes the compiler packages on the same schedule as the React ones.
For now the manual script can only build from `main` but in the future
we can add support for building specific commits

I originally added this prior to the compiler being OSS'd as a "just in
case" feature to panic cancel if something went wrong. Now that the
compiler is already launched this is unnecessary.

Updates the prettier config to format all `.ts` and `.tsx` files in the
repo using the existing defaults and removing overrides.
The first commit in this PR contains the config changes, the second is
just the result of running `yarn prettier-all`.
After this is merged, I'll add it to .git-blame-ignore-revs. I can't do
it now as the hash will change after ghstack lands this stack.

```
Beginning October 4, 2021, all connections to the npm registry - including for package installation - must use TLS 1.2 or higher. You are currently using plaintext http to connect.

This script needs to run from `main` since it commits version bumps for
packages, and those need to point to publicly available hashes. So,
throw an error if we're not already on main.

- Specify a registry for npm publish because otherwise it tries to use
the yarn registry
- `packages` option actually works
This _should_ work now (note last line of output), will test it once we
land this since i want to publish a new version of the eslint plugin
with some important fixes.

I sincerely appreciate the effort to get test262 up and running. This was my
idea, it seemed like a really good way to test our correctness on edge cases of
JS. Unfortunately test262 relies heavily on a few specific features that we
don't support, like classes and `var`, which has meant that we never actually
use this as a test suite.
In the meantime we've created a pretty extensive test suite and have tools like
Sprout to test actual memoization behavior at runtime, which is the right place
to invest our energy. Let's remove?
In order to make changes to the testapp's dependencies, we need to update the
lockfile which means modules need to actually exist. This adds a new script to
just run a build of the packages we sync so that module resolution in the
testapp will work
This combines our scripts and makes it so we no longer need to create a separate
commit to add the forget-feedback/dist directory into the react-forget repo. I
originally did that so I could run tests here, but now that the external repo is
created and has its test suite hooked up to CI, this is now unnecessary friction
to run a sync
Sorry about the thrash in advance! This removes the top level `forget` directory
which adds unnecessary nesting to our repo
Hopefully everything still works
