SecurityPkg: add DeviceSecurity support
This patch implement the SpdmSecurityLib, which is the core of DeviceSecurity. And the SpdmSecurityLib include Device Authentication and Measurement. The other library is to support SpdmSecurityLib.

/**
|
||||
* Copies bytes from a source buffer to a destination buffer.
|
||||
*
|
||||
* This function copies "src_len" bytes from "src_buf" to "dst_buf".
|
||||
*
|
||||
* Asserts and returns a non-zero value if any of the following are true:
|
||||
* 1) "src_buf" or "dst_buf" are NULL.
|
||||
* 2) "src_len" or "dst_len" is greater than (SIZE_MAX >> 1).
|
||||
* 3) "src_len" is greater than "dst_len".
|
||||
* 4) "src_buf" and "dst_buf" overlap.
|
||||
*
|
||||
* If any of these cases fail, a non-zero value is returned. Additionally if
|
||||
* "dst_buf" points to a non-NULL value and "dst_len" is valid, then "dst_len"
|
||||
* bytes of "dst_buf" are zeroed.
|
||||
*
|
||||
* This function follows the C11 cppreference description of memcpy_s.
|
||||
* https://en.cppreference.com/w/c/string/byte/memcpy
|
||||
* The cppreferece description does NOT allow the source or destination
|
||||
* buffers to be NULL.
|
||||
*
|
||||
* This function differs from the Microsoft and Safeclib memcpy_s implementations
|
||||
* in that the Microsoft and Safeclib implementations allow for NULL source and
|
||||
* destinations pointers when the number of bytes to copy (src_len) is zero.
|
||||
*
|
||||
* In addition the Microsoft and Safeclib memcpy_s functions return different
|
||||
* negative values on error. For best support, clients should generally check
|
||||
* against zero for success or failure.
|
||||
*
|
||||
* @param dst_buf Destination buffer to copy to.
|
||||
* @param dst_len Maximum length in bytes of the destination buffer.
|
||||
* @param src_buf Source buffer to copy from.
|
||||
* @param src_len The number of bytes to copy from the source buffer.
|
||||
*
|
||||
* @return 0 on success. non-zero on error.
