Debug groups makes it easier to view from where an error comes from.
The backend can also implement its own callback to make it easier to
follow the API call structure in frame debuggers.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This makes the whole rendering slower (because of sync point) but the
numbers displayed by the draw manager profiler is more precise on some
buggy drivers. They seems to issue the query before the last one ends.
Refactor include:
- Removal of DRWInterface. (was useless)
- Split DRWCallHeader into a new struct DRWCallState that will be reused in the future.
- Use BLI_link_utils for APPEND/PREPEND.
- Creation of the new DRWManager struct type. This will enable us to create more than one manager in the future.
- Removal of some dead code.
Old performance debug was doing queries for every frame even if not debugging perf.
Also, it did not record when a pass was draw multiple time, leading to incorect measurement.
New module also allows to group the timers to limit infos displayed.
Also fix the background CPU draw timer.
