RichText: Format boundaries without DOM (#13697)

* Avoid flickering by setting boundary class when creating the DOM tree * Remove TinyMCE boundaries * Remove TinyMCE so it doesn't interfere with our boundaries * Fix failing unit tests * Only have one boundary class at a time * Remove filterString param * Build in own padding and boundary classes * Update styling * valueToFormat shouldn't create editable tree * Add zero with spaces around formatting * Remove old boundary compatibility code * Update dom diff, prevent browser selection overwrite on boundary * Update UI * Fix inserting format with shortcut * Add check * Remove nbsp inserted by TinyMCE from test * Do not mutate attirbutes object * Fix link e2e tests * WIP * WIP: try boundaries without DOM * Remove zero width space everywhere * Fix e2e tests * Clean up * Revert selection snapshots * Correctly remove dependencies * Add nested boundary test * Add backtick test * Fix annotation tests: they now have boundaries * Merge logic * Fix getActiveFormat test * Update some docs and dependencies * Fix block CSS * Return focus to editable after pressing format button * Update docs * Update changelogs * Add changelog headings * Remove obsolete onFocus class method from Editable * Restore :focus * Update TinyMCE mentions * Use Escape instead of mouse move * Update isHorizontalEdge comment * Add docs for fromFormat * Create test content manually

 Earlier examples used the `createElement` function to create DOM nodes, but it's also possible to encapsulate this behavior into ["components"](). This abstraction helps as a pattern to share common behaviors and to hide complexity into self-contained units. There are a number of components available to use in implementing your blocks. You can see one such component in the snippet above: the [`RichText` component]().

+The `RichText` component can be considered as a super-powered `textarea` element, enabling rich content editing including bold, italics, hyperlinks, etc.
 
 To use the `RichText` component, add `wp-editor` to the array of registered script handles when calling `wp_register_script`.
 
 ```php
 wp_register_script(

 ## Is Gutenberg built on top of TinyMCE?
 
-No. [TinyMCE](https://www.tinymce.com/) is one of the best tools for enabling rich text on the web. In Gutenberg, TinyMCE does exactly that. Nearly every text field you'll find is augmented with TinyMCE for rich text. Whether it be text, lists, or even just a single caption, TinyMCE can be invoked on blocks for rich text enhancements.
