Removing <TextInput autoGrow={true}>

Summary:
`autoGrow` feature was/is totally awesome but... nowadays <TextInput> component is always autoexpandable (on both iOS and Android),
so we don't need JavaScript implementation of this anymore. Sometimes it is even harmfull (see T23403231).

I am sorry, sumkit. You are still awesome. :)
