Auto-hide toolbar in Reviewer (#2262)
* Give webviews a slide-in animation

if reduced motion isn't set.

* Auto-hide toolbar in review mode

moving the mouse above the main webview expands the toolbar. When the mouse leaves the toolbar, it will collapse after a delay of 2s.

* Save some space on bottom toolbars

* Use props for all hard-coded transition durations

and decrease most commonly used duration (200ms) to 150ms.

* Move auto-hide logic into ToolbarWebView

and handle auto-hide specific events in the respective webview subclasses.

* Fix typing issues

* Fix flickering issue

* Add auto_hide_toolbar opt-in to preferences

* Rename hide_toolbar to collapse_toolbar

to better describe the dock-like behaviour.

* Rename setting to minimize_distractions

* Reduce calls to pm in eventFilter

* Run formatter

* Revert setting title to something more specific

* Increase default animation time to 180ms

* Inset toolbar in review mode

when auto-hide is not enabled.

* Use card background on toolbar and add glass effect

* Use flatten/elevate over inset/outset

* Use flatten/elevate over inset/outset

* Update toolbar.py

* Fix toolbar background delay

* Tweak styles

* Use "collapse" instead of "auto-hide"

* Fix background misalignment in collapse mode

* Do not collapse toolbar when pointer is outside MainWebView

* Reduce hide_timer interval to 1000ms

* Use CSS to hide toolbar instead of setting webview height

* Add guard to prevent backdrop-filter: blur on Qt 5.14

* Apply transition to body instead of toolbar

to not complicate things for #2301.

* Fix Qt 5.14 and apply guard globally

* Fix background image scaling difference

* Tweak preference wording (dae)
