React UI: Sidebar with objects and optimizations for annotation view (#1089)

* Basic layout for objects panel

* Objects header

* A little name refactoring

* Side panel base layout

* Firefox specific exceptions

* Some minor fixes

* React & canvas optimizations

* Icons refactoring

* Little style refactoring

* Some style fixes

* Improved side panel with objects

* Actual attribute values

* Actual icons

* Hidden > visible

* hidden -> __internal

* Fixed hidden in ui

* Fixed some issues in canvas

* Fixed list height

* Color picker for labels

* A bit fixed design

* Actual header icons

* Changing attributes and switchable buttons

* Removed react memo (will reoptimize better)

* Sorting methods, removed cache from cvat-core (a lot of bugs related with it)

* Label switchers

* Fixed bug with update timestamp for shapes

* Annotation state refactoring

* Removed old resetCache calls

* Optimized top & left panels. Number of renders significantly decreased

* Optimized some extra renders

* Accelerated performance

* Fixed two minor issues

* Canvas improvements

* Minor fixes

* Removed extra code
