Is your feature request related to a problem? Please describe.
The build currently sets MISSION_DEPS as a list of dependencies which is basically the CFE core and OSAL by default. There is a desire to consolidate all "fixed" entries into a separate defaults file for increased visibility and manageability.

Describe the solution you'd like
These two dependencies can be consolidated into the MISSION_CORE_MODULES default list being proposed in PR #740, but this also depends on #728 so it needs to be implemented separately.

Additional context
This is a dependency of both PR #728 and #740. Original discussion here:
#740 (comment)
