Issue: `SelectionArea` supported gestures should have feature parity with `TextSelectionGestureDetector`
Labels: a: text input,framework,f: gestures,c: proposal,P1,f: selection,team-framework,triaged-framework

`SelectionArea` should have the same supported gestures as `TextSelectionGestureDetector`. This is a pre-requisite for migrating `TextField` from `TextSelectionGestureDetector` to `SelectionArea`. Some of these gestures are also needed for re-implementing `SelectableText` with `SelectionArea` https://github.com/flutter/flutter/issues/104547.

Other details:
On a windows touch screen device the context menu does not show up until the long press ends in editable/static text contexts. On a long press drag it collapses the cursor at the position when the long press ends (editable text). On a long press hold it selects the word on drag start as well as popping up the selection handles (static text). On a long press drag nothing happens (the word at the long press start is selected) (static text).

Normal touch drag does nothing on static text. Consecutive taps also does nothing on static text / consecutive tap + drag.

On a normal touch drag it acts as a mouse drag (editable text). On Editable text consecutive tap / consecutive tap + drag works.

on tap down/tap up works similar to android for editable text, the selection is set on tap up.
