V16: Removes TinyMCE (client-side)

[leekelleher]

Description

Removes TinyMCE RTE property-editor from the client-side codebase.

Note

Tiptap RTE configuration has dependencies on the Dimensions and Max Image Size property-editors, (that were part of the TinyMCE package). To resolve this, the Dimensions property-editor has been relocated to the Property Editors package, and Max Image Size replaces with the general Integer property-editor (with min=0 configuration).

Functionally, it works. Now it remains to nurse the tests through and make sure we properly clean up there. Approving now just in case it works this time and auto-merges 🎉
