Both were defined inline in the header, so the List add/remove bodies
were duplicated into the constructor and destructor of every one of the
150+ ModuleParams-derived classes. Construction and destruction are cold
paths; a call is smaller at each site.
Two consumers reach ModuleParams without px4_platform on the link line
and now need the definitions explicitly: health_and_arming_checks (the
functional-ModeManagement test only pulls it in transitively through
modules__commander, after px4_platform) and the failsafe_web emscripten
build, which compiles module_params.cpp directly.
The smaller constructors let the compiler fully inline the defaulted
FlightTaskDescend constructor on the ITCM boards, so its entry is
dropped from their linker scripts.
Saves 3968 B of .text on px4_fmu-v6x_default.
