Update meson and cmake config to only include openrtx and platform paths.
Update files to use <..> for system and external libraries, ".." for

Given that each radio driver loads its calibration data when initializing
and that the radio driver is strongly platform-specific, there is no strong
need for an intermediate redirection layer through the platform API.
The new codeplug interface was implemented for linux and retrofitted to
all the existing OpenRTX platforms. Limited unit testing was also
implemented.
