Added an explicit type to all $FlowFixMe suppressions to reduce
over-suppressions of new errors that might be caused on the same lines.
Also removes suppressions that aren't used (e.g. in a `@noflow` file as
they're purely misleading)
Test Plan:
yarn flow-ci
We currently abuse the browser builds for Web streams derived
environments. We already have a special build for Bun but we should also
have one for [other "edge"
runtimes](https://runtime-keys.proposal.wintercg.org/) so that we can
maximally take advantage of the APIs that exist on each platform.
In practice, we currently check for a global property called
`AsyncLocalStorage` in the server browser builds which we shouldn't
really do since browsers likely won't ever have it. Additionally, this
should probably move to an import which we can't add to actual browser
builds where that will be an invalid import. So it has to be a separate
build. That's not done yet in this PR but Vercel will follow
Cloudflare's lead here.
The `deno` key still points to the browser build since there's no
AsyncLocalStorage there but it could use this same or a custom build if
support is added.
