Fix includeFontPadding for TextInput placeholder (#26432)

Summary:
The custom font I'm using requires using `includeFontPadding={false}` to be correctly centered vertically. The only case where this is not working is with the placeholder of `TextInput`. To fix it we call `setIncludeFontPadding` on the `EditText` instance, like we do for `Text`.

## Changelog
