TextSource* API updates (#2236)

* Move TextSourceRange static functions to DocumentUtil

getWritingMode is also simplified

* Update Google Docs range to be empty to match other range sources

* Rename imposterContainer to imposterElement

* Add static creation functions

* Add static creation function

* Remove unused collapse function

* Don't select imposter elements

* Refactor setEndOffset

* Adjust argument order for setEndOffset

* Update TextSourceRange constructor

* Remove unused isConnected

* Cache rects

* Fix test

* Remove unused getRect

* Revert "Fix test"

* Remove cachedRect

* Use the source element rect to handle scroll differences

* Writing mode update

* Remove _cachedRects update

This shouldn't be necessary as the imposter is usually detached
almost immediately after scanning, giving no time for the window
to be resized or scrolled.
