Martin Robinson e4822c9c5d script: More thoroughly convert between UTF-16 and UTF-8 offsets in text inputs (#41588) ...

DOM APIs for interacting with selection and text in text inputs
`<input type=text>` and `<textarea>` all accept offsets and lengths in
UTF-16 code units. Servo was not converting all of these offsets into
UTF-8 code units. This change makes it so that this conversion is done
more thoroughly and makes it clear when the code is dealing with UTF-8
offsets and UTF-16 offsets.

Helper functions are added for doing this conversion in both directions
as it is necessary. In addition, a `char` iterator is added for
`TextInput` as it is useful for doing this conversion. It will be used
more completely in the future when a `Rope` data structure is extracted
from `TextInput`.

Finally, specification text is added to all of the DOM implementation
touched here.

Testing: This change includes a new WPT crash test as well as a series
of unit
tests to verify conversion between UTF-8 and UTF-16 offsets.
Fixes #36719.
Fixes #20028.
Fixes #39184.
