feat(ui, dom-adapters): cross-input selection

[neSpecc]

1. UI blocks wrapper now contenteditable which enables cross-input selection (CIS)
2. BlockToolAdapter (all of them for each input) delegates ui:before-input to all affected inputs. To find them, it checks current range and compare its start/end with input position.
3. Delete handler updated: now it has 4 cases:

• when CIS starts in inout
• when CIS ends in input
• when input in-between CIS
• when range is inside the input

4. Enter (Split) logic improved: it is being applied only for cases:

• when CIS starts in inout
• when range is inside the input

5. On any inputType we first remove selected range of CIS
6. CaretAdapter now stores this.#blocks instead of this.#inputs. Thus, we won't care about managing input indexes (with block index) on block removing/moving.
