Make component instance names qualified in topology c++ code gen and JSON dictionary

[jwest115]

• Updated component instance names so they are fully qualified
• Updated component instance names to use C++ qualification (rather than underscores)
• Refactored C++ code gen to use component instance qualified names rather than short names
  • Change also applied to topology config objects, constants, and helper functions for consistency
• Updated C++ code gen so component instances are defined inside their own namespaces
• Regenerated reference test files and updated fpp test files to match these changes

Closes #349

After talking to @thomas-bc, this change will require an update to fprime-gds

[thomas-bc]

In the loaders, we parse the qualified names to infer name of component and channel/event/command
Logic will need to be adapted

Created nasa/fprime#2813 to track the GDS update, will work this in before we merge anything on the FPP side.
