This PR adds a new property on RawKeyEventDataAndroid to hold the deviceId from which that event was generated. The deviceId is been sent from the engine on the changes from this PR: flutter/engine#12958
With this, we will be able to identify from where the event came from, adding the ability to support local multiplayer games, with multiple gamepads.
This adds a canRequestFocus and skipTraversal argument to FocusScope and FocusScopeNode, so that a scope can prevent being traversed.
This allows a fix for a problem in the gallery where the focus while traversing the list of items would sometimes appear to disappear, since it would be focusing things that were in the backdrop that were part of the tree, but were not visible.

This adds a Focus node to the DropdownButton widget, allowing it to receive keyboard focus, and to show a focus highlight. In addition, I added the ability to activate the dropdown using the "enter" key binding (which is bound to ActivateAction in the WidgetsApp).

Flutter tool's service client library tries to "upgrade" sub-components of service responses with higher level model objects. It does this for all members of the response, rather than only those documented in the version it targets, and it errors out when encountering a new type. This causes it to fail when a new field is introduced with a new typed. Clients are required to ignore this.
This re-implements keyboard text selection so that it will work on platforms other than Android (e.g. macOS, Linux, etc.).
Also, fixed a number of bugs in editing selection via a hardware keyboard (unable to select backwards, incorrect conversion to ASCII when cutting to clipboard, lack of support for CTRL-SHIFT-ARROW word selection, etc.).
Did not address the keyboard locale issues that remain, or add platform specific switches for the bindings. All that will need some more design work before implementing them.

In #42533, I disabled the up/down arrows for focus navigation in text fields, but we thought of a better way to do it, so this is that better way.
This change reverts the other change, and instead it tests the context of the node in the action to see if it's an EditableText node. If so, then it doesn't do the navigation action.
The _computeChildren[Width/Height]With[Min/Max]Intrinsics methods in
RenderParagraph overwrite the text painter's placeholder dimensions
in order to compute potential widths and heights for the paragraph.
The placeholder dimensions should be restored to the values computed by
_layoutChildren before painting the text.
