feat(android): textZoom prop to limit scaling issues (#414)

When setting a custom font size in the Android system, an undesirable scale of the site interface in WebView occurs.

I researched that when setting the standard textZoom (100) parameter size, this undesirable effect disappears.

This can be very useful if you need to avoid the scale of content in WebView when changing the size of system fonts, or change textZoom property directly.

Example:

`
<WebView
  textZoom={100}
/>
