Atomics: Fix missing 64bit implementation for 32bit platforms

Blender uses 64bit atomics to manipulate SessionUUID, and these atomics
were not defined on any of 32bit platforms.

While official support is limited to 64bit platforms only, the code
should not make assumptions about bitness or endianess, in terms that
there should be codepaths and fallback (or provision of them) for 32bit
platforms.

This change makes 64bit atomic functions defined for all platforms.
The atomic_test was compiled and successfully tested on i686 and armv7l
platforms. The rest of compilation process of Blender will be very
tedious, so that was not done.

This change is essential, but not necessarily enough to make Blender
compilable on i686 (ability to compile Blender on 32bit platforms was
lost during the 2.91 development).

This is a functional part of original fix done by Brecht in D9577.

Atomics: Cleanup, move defines closer to usage

There is a special defines block needed for ARM on Linux. Move it from
public header to an implementation file.

No functional changes.

This is a non-functional part of original fix done by Brecht in D9577.

Nodes: deduplicate ping pong math operation

The formula did not change. The only side effect of this change should be
that the compositor node now does not divide by zero in some cases.

alembic: fix missing update when changing frames

Tracking: Cleanup, de-duplicate implementation of marker lookup

The logic was duplicated.

Should be no functional changes. The modified function is expected
to give same exact results for all inputs.

On the "caching last-used track" topic. The code was using last_marker
to allow faster lookup of marker closest to the frame. With this
change it is still the case since the BKE_tracking_marker_get() does
cache last used marker.

Geometry Nodes: Fix missing node editor redraw for active modifier

When the active modifier changes, or when its node group changes, the
node editor should redraw, because these actions change its context.

Geometry Nodes: Always use the active modifier for shortcuts

Based on discussion with the team, summarized in T82691, it makes sense
to simplify the shortcut behavior and remove the way the shortcuts
currently activate on hover if there is no active modifier. This commit
also removes the behavior of clearing the active modifier when you
click on blank space in the modifier tab.
