[REQUEST] Add support for the standard ext-foreign-toplevel-list

[keithbowes]

Before opening a feature request

• I checked the next branch to see if the feature has already been implemented
• I searched existing reports to see if it is already requested.

What is the user problem or growth opportunity you want to see solved?

Rofi should support the standard ext-foreign-toplevel-list (introduced in wayland-protocols 1.32) in addition to wlr-foreign-toplevel-management.

How do you know that this problem exists today? Why is this important?

lswt supports both, preferring ext-foreign-toplevel-list. Rofi could do the same. I've considered implementing it myself and sending a PR but I'd like to know it would be accepted before going to the trouble.

Who will benefit from it?

Anyone using a Wayland compositor that doesn't support the proprietary wlr-foreign-toplevel-management protocol.

Rofi version (rofi -v)

Version: 1.7.5+wayland3

Additional information

I don't know why I need to go to the trouble of creating a Gist when this doesn't depend on configuration, but OK.
