fix: Building TX16s firmware with -DDEBUG=YES -DCMAKE_BUILD_TYPE=Debug fails (#3510)

* fixes #3509

Changes:
- change to order of include files
- remove unnecessary include

* revert deletion of include, some radios seem to use it.

* exclude code for CONFIGURABLE_MODULE_PORT for target bootloader
