Fix up ITS header files for internal use in crypto
Merge storage_common.h and internal_trusted_storage.h into a single
file for convenience.
Remove #include of <psa/error.h> which crypto doesn't have yet and
include <psa/crypto_types.h> and <psa/crypto_values.h> instead.
Drop __cplusplus support which we don't need.
Tweak style (whitespace, line breaks, comment formatting) to satisfy
check-names.sh and check-files.sh.
