Text Editing Gestures/Intents/Actions #101151

Currently, gestures related to text editing are handled by TextSelectionGestureDetectorBuilder, with no way to override these gestures practically without using IgnorePointer which blocks all default gestures defined on the text editing widget. The goal here is to build something analogous to the current keyboard shortcuts -> intents -> action system, with defaults that can be practically overwritten by the user.

☔️ To complete this issue we need:

• All pointer-related text editing interactions ported to Intents/Actions, like tapping, long pressing, etc. Text Editing Shortcuts/Intents/Actions #75004
• Support selection all text on triple click Support selecting all text on triple click #63576
• Support double tap drag gesture to select a block of text on iOS Support double-tap-drag gesture to select a block of text #64550
• Single tap on text field to display toolbar Single Tap on TextField does not display Toolbar #48434
• Hide selection toolbar when moving caret/handles Hide selection toolbar on iOS and Android when moving paddles/caret #62193
• Selection toolbar/handle should disappear when clicking outside of it Selection toolbar/handler should disappear when it is opened and user clicks outside of it #72029
• Textfield context menu does not show after focus switch TextField context menus do not show after focus switch #99707

Other issues of note:

• Textfield should receive callbacks from TextSelectionGestureDetector TextField should receive the callbacks from TextSelectionGestureDetector #35187
