Fix #2228, Update UTs to use correct cmd types

Update remaining cases where the CFE_MSG_CommandHeader_t was used for a
command that had no arguments, replacing it with a real data type that
is named according to the command.

In particular, this introduces a "SendHkCmd" type into all modules,
where previously the HK command used CFE_MSG_CommandHeader_t directly.

This includes all the updates to EDS XML files since the Bootes release
where they were last synced.  This includes EDS files for modules that
did not yet have one, and updating the other files to match the current
message structures in Draco.
