Reland Input type=text Shadow DOM With Performance Improvement (#37483)

Depends on #37427.

In addition to the changes introduced by
https://github.com/servo/servo/pull/37065, there are several performance
improvements and nits as follows:
- Use the internal pseudo element for style matching, this will reduce
the performance regression by ~66%.
- Manual construction of the `Text` node inside a text container. This
is followed by the modification of the inner `Text` node instead of
using `SetTextContent` which is more expensive.
- Use `implemented_pseudo_element` instead of
`text_control_inner_editor` `NodeFlag` to handle the special cases that
these elements should follow, specifically the:
  - focus delegation workaround;
  - selections; and
  - line height resolving.
- More documentation.

Servo's side of: https://github.com/servo/stylo/pull/217

Testing: No new unexpected WPT failure, except for the one introduced by
https://github.com/servo/servo/pull/37065/.
Fixes: #36307 #37205
