Integration with vision processor revealed some things that can be cleaned up.

Issues:

• Calling protoc on the default gc/ folder produces a path conflict Python's garbage collector always imports as gc, and this isn't fixable as the interpreter intrinsic always resolved first.
• Defautl protoc cmake function clobbers the include path with used from subfolders/submodules because OUT_DIR internally prepends the output path. Was fixed in A-Team's ssl_ros_bridge FOSS project, but that logic became duplicative with vision processor

Fixes:

• Renames the gc/ folder to gamecontoller. This is reflection but not wire breaking. Resolved the intrinsic path conflict with python garbage collector
• Provides a python helper and documentation to put generate and contain protos in a sslproto module scoping imports and putting them on the path
• Provides an importable cmake helper function that calls protoc in a way that doesn't clobber the import path for cmake c/cpp projects

Making a note, the reflection breaking is expected from the rename. Wire compat is preserved.

Cmake is tested downstream on a vision processor branch and the A-Team ssl_ros_bridge repo and seems to be working cleanly. The python is used on the same vp downstream and the internal wireshark and seems to working
