Changed M_PI to M_PI_F in the matrix library since M_PI is non-standard. (#20458)

Browse Source 
* Changed M_PI to M_PI_F in the matrix library since M_PI is non-standard.

* Added a new M_PI_PRECISE constant definition to px4_platform_common/defines.h to be
used in places when M_PI is desired but shouldn't be used because it is not C standard.

* Added the px4_platform_common/defines.h include to the matrix library math.hpp header to pull
in some non-standard M_PI constants and updated the test files to use those constants.

* Fixed PI constants in matrix helper test to prevent test failure
