Tool System: initial support for UV-sculpt

This currently conflicts with the UV-sculpt toggle being manually set,
ideally this would work more like other paint modes in Blender.

Cleanup: use PyModule_AddIntConstant

Fix invalid flag passed to mesh batch dirty tag

UI: rename Border Select -> Box Select

GP: Move grid parameters to GP object data level

The grid now can be configured by object because this helps to identify objects and allows to define diferent grid parameters for each objects.

Also added a color option.

Fix T56268: display the correct rest shape for B-Bones in Edit Mode.

The rest shape of B-Bones is actually affected by custom handles or
the default connected parent/child mechanism. Ignoring these effects
thus leads to the edit mode shape being different from the actual
rest pose.

This splits the b_bone_spline_setup function that is used to compute
the correct rest and pose shape from pose channels into two parts,
and applies the data structure independent half to edit mode.

In order to access the custom handle settings in Edit Mode, they are
moved to Bone and EditBone, while the bPoseChannel fields are downgraded
in status to a cache for performance. Also, instead of flags, introduce
an enum to specify the handle operation modes, so that new ones could
be added later.

Move B-Bone custom handle settings to Edit mode.

Custom handle settings actually affect the B-Bone rest shape,
so they should be changed in Edit mode rather than Pose mode.
This is necessary to be able to display the correct rest shape
of the bone in Edit Mode.

Also, instead of flags, introduce an enum to specify the handle
operation modes, so that new ones could be added later.
