Bug 1815306 - Truncate tabs tray title to mitigate scroll performance

[jonalmeida]

We truncate the URL as well if we use that, but unlike the url TextView, we do not need to shorten it first.

No tests are needed here for this UI piece which would involve creating/mocking Android Views for limited win. We are transitioning to a Compose tabs tray, so we don't avoid any regressions in this code space.
