test: Only build APM tests if APM is enabled

[Ryanf55]

Description

Compilation of QGC fails on master if you use the custom folder with default options.
I used cmake, on Ubuntu 22, with default options for QGC.

/home/ryan/Dev/qgroundcontrol/test/Vehicle/APMAirframeComponentControllerTest.cc:6:10: fatal error: APMAirframeComponentController.h: No such file or directory
    6 | #include "APMAirframeComponentController.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

You also see a linker error.
