Move all buttons to our custom inline surrounding (#1682)

* Clarify some comments

* Don't destructure insertion trigger

* Make superscript and subscript use domlib/surround

* Create new {Text,Highlight}ColorButton

* Use domlib/surround for textcolor

- However there's still a crucial bug, when you're breaking existing
  colored span when unsurrounding, their color is not restored

* Add underline format to removeFormats

* Simplify type of ElementMatcher and ElementClearer for end users

* Add some comments for normalize-insertion-ranges

* Split normalize-insertion-ranges into remove-adjacent and remove-within

* Factor out find-remove from unsurround.ts

* Rename merge-mach, simplify remove-within

* Clarify some comments

* Refactor first reduce

* Refactor reduceRight

* Flatten functions in merge-ranges

* Move some functionality to merge-ranges and do not export

* Refactor merge-ranges

* Remove createInitialMergeMatch

* Finish refactoring of merge-ranges

* Refactor merge-ranges to minimal-ranges and add some unit testing

* Move more logic into text-node

* Remove most most of the logic from remove-adjacent

- remove-adjacent is still part of the "merging" logic, as it increases
  the scope of the child node ranges

* Add some tests for edge cases

* Merge remove-adjacent logic into minimal-ranges

* Refactor unnecessary list destructuring

* Add some TODOs

* Put removing nodes and adding new nodes into sequence

* Refactor MatchResult to MatchType and return clear from matcher

* Inline surround/helpers

* Shorten name of param

* Add another edge case test

* Add an example where commonAncestorContainer != normalization level

* Fix bug in find-adjacent when find more than one nested nodes

* Allow comments for Along type

* Simplify find-adjacent by removing intermediate and/or curried functions

* Remove extend-adjacent

* Add more tests when find-adjacent finds by descension

* Fix find-adjacent descending into block-level elements

* Add clarifying comment to refusing to descend into block-level elements

* Move shifting logic into find-adjacent

* Rename file matcher to match-type

* Give a first implemention of TreeVertex

* Remove MatchType.ALONG

- findAdjacent now directly modifies the range

* Rename MatchType.MATCH into MatchType.REMOVE

* Implement a version of find-within that utilizies match-tree

* Turn child node range into a class

* Fix bug in new find-adjacent function

* Make all find-adjacent tests test for ranges

* Surrounding within farthestMatchingAncestor when available

* Fix an issue with negligable elements

- also rename "along" elements to "negligable"

* Add two TODOs to SurroundFormat interface

* Have a messy first implementation of the new tree-node algorithm

* Maintain whether formatting nodes are covered or within user selection

* Move covered and insideRange into TreeNode superclass

* Reimplement findAdjacent logic

* Add extension logic

* Add an evaluate method to nodes

* Introduce BlockNode

* Add a first evaluate implementation

* Add left shift and inner shift logic

* Implement SurroundFormatUser

* Allow pass in formatter, ascender and merger from outside

* Fix insideRange and covered switch-up

* Fix MatchNode.prototype.isAscendable

* Fix another switch-up of covered and insideRange...

* Remove a lot of old code

* Have surround functions only return the range

- I still cannot think of a good reason why we should return addedNodes
  and removedNodes, except for testing.

* Create formatting-tree directory

* Create build-tree directory + Move find-above up to /domlib

* Remove range-anchors

* Move unsurround logic into no-splitting

* Fix extend-merge

* Fix inner shift being eroneusly returned as left shift

* Fix oversight in SplitRange

* Redefine how ranges are recreated

* Rename covered to insideMatch and put as fourth parameter instead of third

* Keep track of match holes and match leaves

* Rename ChildNodeRange to FlatRange

* Change signature of matcher

* Fix bug in extend-merge

* Improve Match class

* Utilize cache in TextColorButton

* Implement getBaseSurrounder for TextColorButton

* Add matchAncestors field to FormattingNode

* Introduce matchAncestors and getCache

* Do clearing during parsing already

- This way, you know whether elements will be removed before getting to
  Formatting nodes

* Make HighlightColorButton use our surround mechanism

* Fix a bug with calling .removeAttribute and .hasAttribute

* Add side button to RemoveFormat button

* Add disabled to remove format side button

* Expose remove formats on RemoveFormat button

* Reinvent editor/surround as Surrounder class

* Fix split-text when working with insert trigger

* Try counteracting the contenteditable's auto surrounding

* Remove matching elements before normalizing

* Rewrite match-type

* Move setting match leaves into build

* Change editing strings

- So that color strings match bold/italic strings better

* Fix border radius of List options menu

* Implement extensions functionality

* Remove some unnecessary code

* Fix split range endOffset

* Type MatchType

* Reformat MatchType + add docs

* Fix domlib/surround/apply

* Satisfy last tests

* Register Surrounder as package

* Clarify some comments

* Correctly implement reformat

* Reformat with inactive eraser formats

* Clear empty spans with RemoveFormatButton

* Fix Super/Subscript button

* Use ftl string for hardcoded tooltip

* Adjust wording
