Move __HAVE_FAST_FMA to math_config.h

Browse Source 
Define it consistently with other HAVE_* macros that only affect code
using math_config.h.  This is also closer to the Arm Optimized Routines
code.

double and single precision arithmetics has similar latency and it
has no legacy SVID matherr support, only POSIX errno and fenv
exception based error handling.
__HAVE_FAST_FMA_DEFAULT
Default value for __HAVE_FAST_FMA if that's not set by the user.
It should be set here based on predefined feature macros.
__HAVE_FAST_FMA
It should be set to 1 if the compiler can inline an fma call as a
single instruction. Some math code has a separate faster code
path assuming the target has single instruction fma.
