layout: Stretch <input> inner container to its containing block (#38775)

Browse source 
The `<input>` element inner container should be stretch to its
containing block. This would allow the alignment of the text. This is
done by adding `min-width: 100%`. It is required because we are not
using a custom layout contrary to Firefox and Chrome.

Testing: New Servo specific WPT.
