Describe the contribution

• Fix #221

Moves cf_tbldefs.h so that the compiler doesn't pick up the default platform_inc headers instead of the overridden headers (if they exist) at the mission level. The table structure definitions are not configurable at a platfrom level, much like the majority of other applications.

Testing performed Build/run unit tests

Expected behavior changes Overridden headers at mission level will now be used by cf_tbldefs.h vs the defaults in fsw/platform_inc where the file was formerly co-located.

System(s) tested on

• Hardware: i5/wsl
• OS: Ubuntu 18.04
• Versions: Bundle main + this commit

Additional context None
