Optimize the firmware footprint of the MO_DBG_X macros.
The MO_DBG_X functionality was implemented inside macros only. This approach leads to much duplicated code after preprocessing. This PR moves a large share of the MO_DBG_X functionality into actual C++ functions. A simple measurement for validation showed a significant firmware footprint decrease of ~30 kB.
If using a custom console integration (enabled via
MO_CUSTOM_CONSOLE=1), theMO_CONSOLE_PRINTFmacro also comes at a significant overhead. By moving the message buffer which is allocated on the heap into the data section, the firmware size decreases by further ~10 kB.
