TinyMCE: improve reposition method inline toolbars

* Make sure the toolbar does not overlap the target, unless it is higher than half the visible editor area's height.
* Allow the toolbar to have the preference to position itself above or below the target.
* Cache DOM lookups.
* Simplify the logic and fix various positioning issues.

See #32604.
