Since arm_cde.h includes stdint.h, its use requires the presence of
the right gnu/stub-*.h, so make sure to include it when checking the
arm_v8*m_main_cde* effective targets, otherwise we can decide CDE is
supported while it's not really (all tests that use arm_v8m_main_cde*
also include arm_cde.h aynway).
Similarly for the effective targets that also require MVE.
This makes several tests unsupported rather than fail.
