Continuing moving macros out of math-tests.h to smaller headers
following typo-proof conventions instead of using #ifndef, this patch
moves the EXCEPTION_TESTS_* macros for individual types out to their
own sysdeps header.
As with ROUNDING_TESTS_*, there is no need to define these macros if
FE_ALL_EXCEPT == 0 and the individual exception macros are undefined;
thus, math-tests-exceptions.h headers are only needed for soft-float
ARM and RISC-V, while the other cases that defined these macros do not
need to do so (and the associated math-tests.h headers are thus
removed without needing replacement by math-tests-exceptions.h
headers).
Tested with build-many-glibcs.py.
