Add tkinter Text methods edit_canundo() and edit_canredo() #151674
Description
Feature or enhancement
The Tk text widget supports the pathName edit canundo and pathName edit canredo subcommands, which report whether the undo and redo stacks are non-empty. tkinter currently wraps edit modified, edit redo, edit reset, edit separator and edit undo, but not edit canundo/edit canredo. They are only reachable through the generic, undocumented Text.edit() passthrough.
I propose adding two convenience methods to tkinter.Text:
- edit_canundo() — return True if undo is possible (the undo stack is not empty), False otherwise.
- edit_canredo() — return True if redo is possible (the redo stack is not empty), False otherwise.
Both return a proper bool.

This is one of a few Tk text subcommands not yet wrapped by tkinter; sync/pendingsync are tracked separately.

Thank you for advancing the tkinter wrapping of tk. I don't know if I would ever use these, and the sync methods, but I am in favor of having them available.

I plan to add wrappers for all Tk commands, if they makes any sense.
