Nathan Hunzaker a079011f95 🔥 Stop syncing the value attribute on inputs (behind a feature flag) (#13526)
* 🔥 Stop syncing the value attribute on inputs

* Eliminate some additional checks

* Remove initialValue and initialWrapper from wrapperState flow type

* Update tests with new sync logic, reduce some operations

* Update tests, add some caveats for SSR mismatches

* Revert newline change

* Remove unused type

* Call toString to safely type string values

* Add disableInputAttributeSyncing feature flag

Reverts tests to original state, adds attribute sync feature flag,
then moves all affected tests to ReactFire-test.js.

* Revert position of types in toStringValues

* Invert flag on number input blur

* Add clarification why double blur is necessary

* Update ReactFire number cases to be more explicite about blur

* Move comments to reduce diff size

* Add comments to clarify behavior in each branch

* There is no need to assign a different checked behavior in Fire

* Use checked reference

* Format

* Avoid precomputing stringable values

* Revert getToStringValue comment

* Revert placement of undefined in getToStringValue

* Do not eagerly stringify value

* Unify Fire test cases with normal ones

* Revert toString change. Only assign unsynced values when not nully
