Add a Window property to make a window not appear in the taskbar and application switcher

[EiTaNBaRiBoA]

Describe the project you are working on

I am working on a widget software for windows and the user can creates different widgets (which are windows in godot) with many types of functionality.

Describe the problem or limitation you are having in your project

The software is appearing in the taskbar and due to many functionality from the widgets, the icon in the taskbar is unrelated and also being irrelevant to the user

Describe the feature / enhancement and how it helps to overcome the problem or limitation

The feature would help me overcome the issue by hiding the godot app from the taskbar, not interfering with the user workflow or filled with unnecessary icons.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

settings -> window -> showIntaskbar checkbox to check or uncheck (boolean)
or

get_viewport().showInTaskbar = true/false

If this enhancement will not be used often, can it be worked around with a few lines of script?

get_viewport().showInTaskbar = true/false

Is there a reason why this should be core and not an add-on in the asset library?

It's just one line of code to enable or disable / Single checkmark in the project settings. no additional configurations are needed.
