GPencil: Fix error when stroke has 0 points

It's possible create a stroke with 0 points using python

Cleanup: Removing unused parameter.

Fix T74604: A.N.T Landscape Erode function reports error

Although indicated, the `rna_Object_active_vertex_group_set`
function was missing.

Fix missing NULL terminator for new brush option

Fix key detection issues introduced by D7229

Removing the GHOST_kKeyUnknown check from processKeyEvent() produces
epeated unknown key events whenever a modifier key is held down, due
to the way ghost uses GHOST_kKeyUnknown as a filter value for modifier
key events.

Sculpt: Pose Brush Face Sets origin mode

This commit introduces a new mode for calculating the positions and
weights of the IK segments in the Pose Brush based on the Face Sets.

The first segment of the chain will always include all face sets inside
the brush radius and it will propagate until the boundary of the last
face sets added in the flood fill. Then consecutive connected face sets
are added to the chain until the chain length limit is reached or all
face sets of the mesh are already part of the chain.

This feature enables complete control over the pose brush origins in
case that is needed. Also, with this mode, the user can have a library
of base meshes with face sets already configured to get to the initial
pose as fast as possible.

Rename Edge Automasking to Mesh Boundary Automasking

This makes more clear what this automasking operation does and helps to differenciate it from the future face sets boundary automasking.

Sculpt: Weight normal and area sampling towards the brush center

Previously, all vertices inside the brush radius were taken into account
equally when calculating the sculpt normal and area. This was causing
artifacts and unpredictable results with large brushes or meshes with
curvatures, as the strongest deformation point of all brushes is usually
in the center. By weighting the vertex normal and position towards the
center when sampling, all brushes should now behave in a more
predictable way in non-uniform surfaces.

Fix T74637: Reset face set data when disabling dyntopo

Last time I checked Face Sets were preserved in a more or less
predictable way when modifying the mesh with dyntopo. As it looks that
in some problems this may cause bugs and you can't see or use face sets
when modifying the topology of the mesh whith dyntopo active, it is
probably better to reset them when going from dyntopo to mesh. This way
you know that you are always going to get a predictable face sets state.

GPencil: Small tweaks to Fill material panel

Install_deps: Do not wipe out `WITH_PYTHON` CMake options.

This is annoying when one want to use system python and hence disables
the `WITH_PYTHON_INSTALL` options...

install_deps: Enable PIC in Python static library.

Update for D3078, I think it should be fixed

Benefits:
- after installing python 3.7 with `./build_files/build_environment/install_deps.sh`, user will be able to run `make bpy` without linking error:

To prevent errors like `/opt/lib/python-3.7.4/bin/python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory`, add python .so lib to ldconfig
