The code didn't check if we should initialize the transform auto IK parameters.
Cleaned up the code a bit too.

Fix T66812: Particles + Build Modifier = Crash

Particles can not be used with a destructive modifiers, so we can not
maker such configuration fully reliable.

Not sure this specific setup ever worked in 2.7x, maybe DM index was
somehow reset somewhere in particle system in older Blender version,
or maybe all of Blender version were crashing.

Anyway, seems to be very easy to avoid obvious index past the array
boundary in the mapping,

Fix T66941: GPencil wrong interpolation calculation for last keyframe

The range used for frames was wrong and the last keyframe was way off of the correct place.

Thanks to @MagnumOctopus for catching the bug.

Fix T64827 (part two): "Batch-Generate Previews" fails with certain files

Some values (not properly handled by do_versions?) could cause
'rna_backup_restore()' to throw an error resulting in the whole preview
generation not being saved to the .blend file.

I've checked folowwing demo files:
- race_spaceship.blend
- wasp_bot.blend

Here the offending seetings were:
- `UnitSettings` (`length_unit`, ...)
- `FFmpegSettings` (`ffmpeg_preset`, ...)

For now, these are now excluded in `exclude_props`

Fix T66668: frame selected bone not working in weight paint mode

'viewselected_exec()' [which uses evaluated view layer] would query
BASE_SELECTED flag, but it was not set on base_eval, but on its
base_orig.

reason for this is 'ed_object_select_pick()' would modify base flags
[through 'ED_object_base_select()'], but not tag scene
ID_RECALC_BASE_FLAGS.

thx @sergey for hinting.
