Fix Boundary Brush symmetry with no constant falloff

When using constant falloff symmetry was working fine because the same
deformation is applied twice on the same vertices. When using no
constant falloffs, the deformation is different between symmetry passes,
so vertices need to be separated by symmetry areas to get the right
deformation from its symmetry pass without being overwriten by the next
one.

GPencil: Remove unused variable and fix memory leak

This was missing in previous commit

Sculpt: Boundary Brush Falloff Types and Offset

This adds the boundary_falloff_type and boundary_offset to control how the
falloff of the Boundary Brush is applied.

Boundary Origin Offset is the same concept as the Pose Origin offset in
the Pose Brush. It is a multiplier that adds extra length to the brush
radius to locate the deformation pivot further from the boundary without
affecting the falloff.

The Falloff type includes Constant (previous default), brush radius, loop
and loop and invert. Loop and Loop and Invert can be used to create
deformation patterns in a mesh.
