Add bindings for floating window

[Steven Guh]

Problem

The floating window is supported in Nov 2023 release -- https://code.visualstudio.com/updates/v1_85

I feel like we should have key bindings to support these new operations:

• View: Copy Editor into New Window (workbench.action.editor.copyWithSyntaxHighlightingAction)
• View: Move Editor into New Window (workbench.action.editor.moveEditorToNextWindow)
• View: Copy Editor Group into New Window (workbench.action.editor.copyGroupToNextWindow)
• View: Move Editor Group into New Window (workbench.action.editor.moveGroupToNextWindow)
• View: New Empty Editor Window (workbench.action.newWindow)

Solution

Not really sure where is the right place for these. Maybe SPC F for frame?

spc F sounds good!
