[Lens] Allow user to drag and select a subset of the timeline in the …

…chart (aka brush interaction) (#62636)

* feat: brushing basic example for time histogram

* test: added

* refactor: simplify the structure

* refactor: move to inline function

* refactor

* refactor

* Always use time field from index pattern

* types

* use the meta.aggConfigParams for timefieldName

* fix: test snapshot update

* Update embeddable.tsx

removing commented code

* fix: moment remov

* fix: corrections for adapting to timepicker on every timefield

* fix: fix single bar condition

* types
