[ARM] Fix definition of __ARM_FEATURE_NUMERIC_MAXMIN

Definition of __ARM_FEATURE_NUMERIC_MAXMIN checks for
TARGET_ARM_ARCH >= 8 and TARGET_NEON being true in addition to
TARGET_VFP5. However, instructions covered by this macro are part of
FPv5 which is available in ARMv7E-M architecture. This commit fixes the
macro to only check for TARGET_VFP5.
