DevTools window enhancements - open directly to hovered control & remember window layout

[moon6969]

Nearly every time I need DevTools I have to:
→ F12
→ Drag window from above the debugee window
→ Ctrl-Shift on debugee window target control
→ Go back to DevTools window & resize one or more columns so I can see required data.

I suggest the DevTools user experience would be improved by

1. Automatically performing Inspect (Ctrl-Shift) on the control under cursor when F12 is pressed
2. Optionally saving the users changes to:
   • window size
   • window position & state
   • column widths
   • options (under View & Overlays menus)

This is a similar suggestion to Issue #6055, but that was resolved by DevToolOptions.StartScreenIndex (PR #6074) rather than remembering the last use.

DevToolOptions.Size helps a little, but the default column width mean "Value Frame" data is usually truncated.

DevToolOptions.StartScreenIndex helps keep the DevTools window from covering the debugee window, but forces WindowState.Maximized for some reason - uncomfortable on a 4k or ultra-wide monitor (and if you un-maximise it's positioned at screen.Bounds.TopLeft).

Would it be feasible to get the DevTools window to remember it's last size, position, internal column layout etc.?
