Check input P7Data is a wrapped ContentInfo structure or not. If not construct
a new structure to wrap P7Data.
Caution: This function may receive untrusted input.
UEFI Authenticated Variable is external input, so this function will do basic
check for PKCS#7 data structure.
@param[in] P7Data Pointer to the PKCS#7 message to verify.
@param[in] P7Length Length of the PKCS#7 message in bytes.
@param[out] WrapFlag If TRUE P7Data is a ContentInfo structure, otherwise
return FALSE.
@param[out] WrapData If return status of this function is TRUE:
1) when WrapFlag is TRUE, pointer to P7Data.
2) when WrapFlag is FALSE, pointer to a new ContentInfo
structure. It's caller's responsibility to free this
buffer.
@param[out] WrapDataSize Length of ContentInfo structure in bytes.
@retval TRUE The operation is finished successfully.
@retval FALSE The operation is failed due to lack of resources.
