Cleanup: Remove unused original pointer in Sequence

Fix T78835: Ghosting audio after using undo

The root of the issue comes to the fact that sub-data pointers were
used to match strips before/after copy-on-write. The undo system might
re-use sub-data pointers after re-allocating them, making it so that,
for example, pointer used by sound strip is later re-used by video
strip.

This fix takes an advantage of recently introduced per-sequence UUID
and uses it to match sequences before/after copy-on-write.

Sequencer: Ensure UUIDs are updated when needed

Document cases where it seems that they need to be updated, but where
the proper behavior is to not update the UUID.

Depsgraph: Add command line argument to debug UUIDs

Will trigger code paths which makes sure UUIDs are generated and
are unique.

Enabled with --debug-depsgraph-uuid (which is also implied by
--debug-depsgraph).

Sequencer: Add session UUID check function

Is aimed for use during development and debug, to help
verifying that operations do not leave sequences with
invalid UUIDs.

Sequencer: Add session UUID management to Sequence

This is the first step for having sequences covered with session UUID
with the goal to remove code which uses original sequence pointer to
match sequences.

Currently this UUID is maintained on file load, allocation and leaf
duplication function.There are more cases to cover and ensure UUID
is re-generated or re-used when needed. It will be done as follow-up
development.

Sequencer: Add session UUID field to the Sequence DNA

BLI: Initial implementation of generic session UUID API

Covers basics like generation of new UUID.

Also contains code needed to use the SessionUUID as a key in the Map.

Add generic session UUID structures to DNA

Allows to use pre-defined structure for session UUIDs in all data
structures which needs it: pose channels, sequencer strips, modifiers.

The goal of all this is to have a reliable way of matching original
and copy-on-written versions of data, so that it's possible to
preserve runtime caches.

UI: fix buttons ranges not properly updated when tabbing to next/previous
button

This was reported for the FCurve modifier restrict ranges, but might fail
elsewhere, too. Reason is that the post_but has its range (hardmin/
hardmax etc) set before the updates to the active button take place, so
changes here dont end up on the post_but (even though the RNA range
function is properly called for a new defined button - new one is not the
same as the post_but though).

Now update the ranges on the post_but when that gets active.
