We implement setting of the caret using HyperText rather than TextLeafPoint because caret stuff, including events, still uses HyperText internally for now. This moves the async IPDL method already used on non-Windows into the base classes so Windows can use it. We keep the COM implementation for Windows RemoteAccessible without the cache. SetCaretOffset was moved into HyperTextAccessibleBase and platform methods were updated accordingly. Finally, I did some drive-by cleanup (no user impact) and changed GetCaretOffset in ATK and XPCOM to use HyperTextAccessibleBase. GetCaretOffset was moved to the base some time ago, but ATK and XPCOM weren't updated at the time. Differential Revision: https://phabricator.services.mozilla.com/D147852
