USD Exporter: clarified export options in the UI

- "Only Export Selected Objects" ? "Selection Only", as this is the
standard used in other exporters.
- "Evaluation Mode" ? "Use Settings for", as this is clearer for users
who aren't as familiar with the technical details of the depsgraph.
- "Use Instancing" ? "Instancing", and moved the checkbox to the end of
the option list into its own box "Experimental". This looks a bit
cleaner than just plonking "EXPERIMENTAL" in the checkbox label.

Cleanup: ARegion.sizex/y should not be used to access region size

This should only be used to change and recalculate region sizes in a DPI
independent way. To get the size with DPI applied, ARegion.winx/y should
be used instead.
Added note on this in comment.

Docs: roll version to 2.83 for master

Fix T71491: Sculpt Brush Text Color

When text drawing is disabled in the viewport the color of the sculpt
brh is set to the last used one. In th Light theme this is black what
makes it totally not visible.

This change will render the brush text using `TEXT_HI` as this is the
last one set when the text overlay is on.

Fix T71908: Animated properties are lost after frame-post handler

The issue was caused by special handling of animation update after
manual edits in frame_post handler: to avid loss of manual edits
done on top of animated property. This was done as a separate pass
for non-animation update after frame_post did modifications.

This caused some other side-effect: non-modified animated property
was re-setting to the value which is used in the viewport.

Idea of this solution is simple: preserve values which came from
animation update through copy-on-write process. The actual process
of this is a bit involved: need to decode RNA path and do it twice
since f-curve might point to a sub-data which pointer will change.
Since this is only done for non-active depsgraph (aka depsgraph
used for render pipeline) this is probably fine since all this
extra overhead is just a fraction of overall render process.

Version cycle 2.83, master is now in alpha and open for new work and features

Merge branch 'blender-v2.82-release'

Version cycle to 2.83 alpha for master.

Cleanup: group event_query functions in header

Cleanup: name wm_event_modalkeymap_begin/end

Relocate & name functions to make it clear calling begin
should be followed by a call to end.

Also group locking & report functions.

Cleanup: move public event queries into their own file

event_system.c has been collecting a lot of different functionality,
move generic query/access functions into their own file,
since these are used by operators and other parts of the windowing code
and aren't part of low level event handling.

Also move public last-property API to wm_operators.c.

Version 2.82 cycle to beta for bcon3, stabilizing period

Cleanup: use doxy sections in wm_event_system.c

Correct last commit, restore the double-click state for modal events

Fix T72999: Fast keystrokes ignored for operators with modal keymaps

Logic to convert double-click events into press events wasn't running
in the case an operator had a modal keymap, causing bevel for e.g.
to ignore keys pressed quickly.

Change event handling logic so modal handlers never
receive double click events, so checks for press/release are reliable.

While this is an old issue for mouse events in practice it wasn't
a problem since the first event typically executed/canceled.
Support for keyboard double-click exposed the problem
for all modal operators that take numeric input.
