[electron] The Select All command executes incorrectly

[kittaakos]

Description

I have forcefully enabled all menu items in electron to see the Selection menu (#6425). When I did a Select All, not the focus item was selected, but the monaco editor's content. It works perfectly in the browser.

Electron:

Browser:

Note, the Select All does not work in electron either when I close the editor and have the focus on an input.

Reproduction Steps

OS and Theia version:
macOS, f255f5a

We have to distinguish between Theia command and pure DOM command executions just like VS Code does:
https://github.com/microsoft/vscode/blob/f7118fd368dd088d66ed95527e5c16e9504c4081/src/vs/editor/browser/controller/coreCommands.ts#L1648-L1655

https://github.com/microsoft/vscode/blob/f7118fd368dd088d66ed95527e5c16e9504c4081/src/vs/editor/browser/controller/coreCommands.ts#L1607-L1611

We have to do the same for Undo and Redo.

VS Code makes differences whether the text has the focus in the active editor or not.

https://github.com/microsoft/vscode/blob/f7118fd368dd088d66ed95527e5c16e9504c4081/src/vs/editor/browser/controller/coreCommands.ts#L1602-L1603

We don't:

theia/packages/editor/src/browser/editor-keybinding-contexts.ts

Lines 25 to 28 in 9457f80

	/**
	* ID of a keybinding context that is enabled when the active text editor has the focus.
	*/
	export const editorTextFocus = 'editorTextFocus';

There is strictEditorTextFocus for only text focus.
