/**
Extracts the attached content from a PKCS#7 signed data if existed. The input signed
data could be wrapped in a ContentInfo structure.
If P7Data, Content, or ContentSize is NULL, then return FALSE. If P7Length overflow,
then return FALSE. If the P7Data is not correctly formatted, then return FALSE.
Caution: This function may receive untrusted input. So this function will do
basic check for PKCS#7 data structure.
@param[in] P7Data Pointer to the PKCS#7 signed data to process.
@param[in] P7Length Length of the PKCS#7 signed data in bytes.
@param[out] Content Pointer to the extracted content from the PKCS#7 signedData.
It's caller's responsibility to free the buffer with FreePool().
@param[out] ContentSize The size of the extracted content in bytes.
@retval TRUE The P7Data was correctly formatted for processing.
@retval FALSE The P7Data was not correctly formatted for processing.
