Floating Menus - UI rework (#5980)

## Summary

Enhancing and further modernizing the UI, giving users more usable area
whilst keeping farmiliar positioning and feel of elements.

## Changes

- **What**: Significant restructure of the UI elements, changing
elements from large blocks to floating elements, updating:
- Side toolbar menu (floating style, supports small/normal mode,
combines to scroll on height overflow)
- Bottom tabs panel (floating style, tabs redesigned)
- Action bar (support for docking/undocking menu)
    - Added login/user menu button to top right
- Restyled breadcrumbs (still collapse when overflows)
- Add litegraph support for fps info position (so it isn't covered by
the sidebar)

- **Breaking**: 
- Removed various elements and added new ones, I have tested custom
sidebars, custom actions, etc but if scripts are inserting elements into
"other" elements they may have been (re)moved.
- Remove support for bottom menu
- Remove support for 2nd-row tabs
