Handle cases where selection API doesn't apply
The selection API only applies to certain <input> types:
https://html.spec.whatwg.org/multipage/#do-not-apply
This commit ensures that we handle that correctly.
Some notes:
1. TextControl::set_dom_selection_direction now calls
set_selection_range(), which means that setting selectionDirection will
now fire a selection event, as it should per the spec.
2. There is a test for the firing of the select event in
tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/select-event.html,
however the test did not run due to this syntax error:
(pid:26017) "ERROR:script::dom::bindings::error: Error at http://web-platform.test:8000/html/semantics/forms/textfieldselection/select-event.html:50:11 missing = in const declaration"
This happens due to the us of the "for (const foo of ...)" construct.
Per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of
this should actually work, so it's somewhat unsatisfying to have to
change the test.
3. I removed tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/selection-not-application-textarea.html
because it doesn't seem to add any extra value - the selection API
always applies to textarea elements, and the API is tested elsewhere.
4. If an `<input>`'s type is unset, it defaults to a text, and the
selection API applies. Also, if an `<input>`'s type is set to an
invalid value, it defaults to a text too. This second case doesn't
currently work, and I'll need to do more restructuring of the code in
a future commit. See discussion with nox in IRC:

to account for this second case.

This allows us to have ensure_data() and clear_data() functions on the TElement
trait, instead of hacking around it adding methods in random traits.
This also allows us to do some further cleanup, which I'd rather do in a
followup.
Clean up HTMLImageElement::handle_event
Area::hit_test now uses a reference instead of taking ownership
Fix trailing whitespace
Unalign => in match
Fix Area::hit_test tests to reflect updated function signature
This will go back down soonish when NonZero stablizes and we can use it in
StyleArc, which I expect will be long before the memory overhead here matters.

Sometimes clippy gets outdated by months, and its current support setup
means that each Servo component need to opt into it by depending on
the plugins crate manually, and not all components do that.
