cleanup type usage

free types when Blender exits

use guarded allocator for some core types

store types in global variables

Do not use a reference counter for Types

Types can be expected to stay alive until Blender exists.
This also works well with the fact that they are identified

Furthermore, the number of types is fairly low, but they
are passed around a lot. Maintaining a thread-safe reference
count seems to be unnecessary overhead.

remove AttributeArrayCore class

It worked well, but having it does not provide enough value
to justify the additional complexity.
