This puts all static functions in geometry node files into a new namespace. This allows using unity build which can improve compile times significantly (P2578). * The name space name is derived from the file name. That makes it possible to write some tooling that checks the names later on. The file name extension (`cc`) is added to the namespace name as well. This also possibly simplifies tooling but also makes it more obvious that this namespace is specific to a file. * In the register function of every node, I added a namespace alias `namespace file_ns = blender::nodes::node_geo_*_cc;`. This avoids some duplication of the file name and may also simplify tooling, because this line is easy to detect. The name `file_ns` stands for "file namespace" and also indicates that this namespace corresponds to the current file. In the beginning I used `node_ns` but `file_ns` is more generic which may make it more suitable when we want to use unity builds outside of the nodes modules in the future. * Some node files contain code that is actually shared between different nodes. For now I left that code in the `blender::nodes` namespace and moved it to the top of the file (couldn't move it to the bottom in all cases, so I just moved it to the top everywhere). As a separate cleanup step, this shared code should actually be moved to a separate file. Differential Revision: https://developer.blender.org/D13330
