small fixes for manta script export

Fix: Ensure that LANPR panel is only enabled when that engine is enabled

- Fixed incorrect COMPAT_ENGINES define

- Removed poll() callback that was preventing the COMPAT_ENGINES
set from working

- Have panel opened by default (since it doesn't need to stay collapsed
when other engines are active anymore)

Example commit for fixing panel visibility when LANPR is enabled

Following the examples here (for the Scene/KeyingSet settings),
all general non-engine-specific panels should include "BLENDER_LANPR"
in the COMPAT_ENGINES set.

Automatically refresh viewport when changing LANPR settings

Use the messagebus struct-subscription methods here (as used for EEVEE settings)
so that changing rendering methods or other settings immediately refreshes
the viewport instead of requiring the user to click on the viewport to force
a redraw.

Fix compiler warnings (use 0 in enums for no icon, not NULL) + whitespace (mixed tabs/spaces)

Compile Fix: Branch now compiles when WITH_OPENSUBDIV is disabled

Adjusted vertex wig and edge flip opti
