uVisor: Add header file copy to importer script

The core_cmSecureAccess.h file contains secure-access APIs that are a
good candidate for a proposal to CMSIS. At the moment we maintain these
APIs ourselves in ARMmbed/uvisor, and will push updates to
ARMmbed/mbed-os when running our usual importer script.
