fix(android): initial measuring tweaks (#784)

# Summary

This fixes a bug where the component's initial height calculation would
break if `defaultValue` was provided without an explicit `fontSize` in
`htmlStyle` prop. The root cause was a mix of a bad initial estimate and
invalid measurements caching:

During `initialMeasure`, missing a passed `fontSize` in props, meant it
defaulted to 0, which caused the entire height estimate to be wrong. I
fixed this by adding a fallback to the default font size, matching how
`EnrichedText` measurements already handle it.

After `initialMeasure`, `setValue` (caused by the present `defaultValue`
prop) is run, which tries to update the shadow node state, but
`stateWrapper` is still `null`. This caused the `MeasurementStore`
internal cache to be out of sync with the actual shadow node's state.
Fixed this by providing an early return in `invalidateLayout()` - we
don't call `Measurement.store()` at all, if `stateWrapper` is
unavailable.

I've also tweaked two small things: in `EnrichedTextInputShadowNode.cpp`
the `forceHeightRecalculationCounter_` was never initialized before
accessing its value, which would make it have random, garbage values.
I've also adjusted the provided `forceHeightRecalculationCounter` to the
`stateWrapper`, as its value was always pre-increment during
`invalidateLayout()`. I believe it's better to have the shadow node's
and component's counters' values consistent.

Sometimes the `setValue`'s layout invalidation could run before the
`initialMeasure`. That made the `MeasurementStore` cached measurements
correct from the start, as after `setValue` runs, the actual component's
size is measured, not estimated like it's the case with
`initialMeasure`. You can see this race condition in the attached video.

## Test Plan

I've provided a modified example app, so you can see the bug yourself -
you can run

```sh
git checkout 212b2a3
```

and then you can check out how it works after the fix

```sh
git checkout 4c47809
```
