Build issues when building with ARM_MATH_SIZE_MISMATCH defined are corrected.
Improvement to the tests to track ARM_MATH_SIZE_MISMATCH error detection.
Solve most of f16 issues. But there are still some remaining
build issues with gcc10q4.
2 functions are reverting to scalar version when build with gcc on M55.
(Since Helium versions of those functions are not building).
