Remove the need for isFormInput prop in Form

[luacmartins]

Problem

Right now we use a isFormInput prop to decide when to pass form props to a child component. There's a disconnect between the name and purpose of this prop, which can be confusing. We could make this implementation simpler and remove the need for isFormInput altogether.

Why is this important

It makes the code less confusing and DRY, simplifying the usage of form inputs.

Solution

1. Figure out some logic to automatically pass form props to inputs only, i.e. excluding View, Text, ScrollView, etc.
2. Remove all usages of isFormInput from the code base.

We are waiting to work on this after the Form refactors are done, so it doesn't confuse contributors.
