Geometry Nodes: Add STL Import Node

Browse Source 
This commit adds an initial STL import node, the first of the nodes from the
current Google Summer of Code Project [0]. The importer is refactored to
output a mesh pointer, and a node is added to wrap around the importer.
The node supports error messages from the importer. A new experimental
option is added to hide the nodes by default until they're ready to be exposed
generally.
