Add support for AppCheck, Analytics, and Functions sdks.

[justjish]

Description

• Create proposal issues for supporting Firebase Analytics, Firebase Functions, and allowing 'dist' to exist in svn.
• Add useInitAppCheck useAppCheck AppCheckProvider
• Add useInitAnalytics useAnalytics AnalyticsProvider
• Add useInitFunctions useFunctions FunctionsProvider
• Add AppCheck examples for withSuspense and withoutSuspense
• Add Analytics examples for withSuspense and withoutSuspense
• Add Functions examples for withSuspense and withoutSuspense
• Add Functions SDK Test? Maybe leave out of this PR
• Allow for dist folder to exist in repo to allow users to use yarn add http://github.com/.../reactfire#[branch] ... todo produce build during pre-commit check?

Code Cleanup

• RemoteConfig now uses rxfire for getValue, getString, getBoolean... rather than just having duplicate code.
• Use objectVal from rxfire for database
• Reference [api].sdk.app.name for all app name checks
• Remove/Convert //@ts-ignore to //@ts-expect-error
• Update firestore withSuspense example so that it doesn't spit out error @ runtime.
• Update dev-dependencies to nearest non-breaking changes.

Hi @sujishpatel thank you for your contribution! We really appreciate all of this work, but it is difficult for us to review a PR with so many different changes. Would you be up for breaking this apart into a few PRs and issues? My suggestion for breaking this into pieces is:

Individual PRs

• Functions (I'd be happy to contribute tests if you open up a PR)
• App Check: I have a PR started (add App Check #430), so let's collaborate there.
• Analytics: @shiiinji has a PR started (useAnalytics missing in ReactFire v4 #429 #431), so let's collaborate there.
• use rxfire for RemoteConfig
• Reference [api].sdk.app.name for all app name checks
• Update dev-dependencies to nearest non-breaking changes
• Remove/Convert //@ts-ignore to //@ts-expect-error

Please file an issue for discussion

• dist folder: Let's discuss and get @jamesdaniels input
• Update firestore withSuspense example so that it doesn't spit out error @ runtime: can you please file an issue that describes the error?

Other

• Use objectVal from rxfire for database: this was fixed here, so I don't think it is needed any more

Thank you again for your hard work! If you can break your changes out into multiple PRs, we'll get them reviewed and merged as quickly as possible.
