Jon Leighton 0461681818 Refactor implementation of TextControl 
The intention here is to make the flow more explicit. I.e. rather than
calling `self.dom_select()` and relying on the programmer to
know/realise that this method is provided by a trait, we call
`self.selection().dom_select()` and the programmer can inspect the
definition of `self.selection()` to follow the code.

This came out of a discussion with KiChjang here:

https://github.com/servo/servo/pull/19544#discussion_r156167044

Note that I tried to make "selection" be a member field of
HTML{Input,TextArea}Element but it opened up a whole can of worms with
lifetimes, so it seemed simpler to not do that since it is not
essential for this code to work.
