Avoid `Window::GetComputedStyle` when checking for `display: none`
<!-- Please describe your changes on the following line: -->
Refactored Window::GetComputedStyle to use Element::Style.
Not sure which tests are relevant, but I've ran the dom, fetch & 2dcontext wpt tests. They don't seem to give errors.

Disallow mutating the internals of TextInput
The TextInput::assert_ok_selection() method is meant to ensure that we
are not getting into a state where a selection refers to a location in
the control's contents which doesn't exist.
However, before this change we could have a situation where the
internals of the TextInput are changed by another part of the code,
without using its public API. This could lead to us having an invalid
selection.
I did manage to trigger such a situation (see the test added in this
commit) although it is quite contrived. There may be others that I
didn't think of, and it's also possible that future changes could
introduce new cases. (Including ones which trigger panics, if indexing
is used on the assumption that the selection indices are always valid.)
The current HTML specification doesn't explicitly say that
selectionStart/End must remain within the length of the content, but
that does seems to be the consensus reached in a discussion of this:
https://github.com/whatwg/html/issues/2424
The test case I've added here is currently undefined in the spec which
is why I've added it in tests/wpt/mozilla.

Fixes#17176.

Fixes#19648.
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.

Add layout RPC query for getting an element's style
This enables us to implement Element::has_css_layout_box() in a more
direct way, and also enables us to remove some of the existing more
specific queries.
Fixes#19811.
