Zhang, Chao B dd577319e8 SecurityPkg Tpm2CommandLib: Fix TPM2.0 response memory overflow
TPM2.0 command lib always assumes TPM device and transmission channel can
respond correctly. But it is not true when communication channel is exploited
and wrong data is spoofed. Add more logic to prohibit memory overflow attack.

Yao, Jiewen b1b1d64699 SecurityPkg: Correct data copy in Tpm2NvReadPublic.
1) NvPublic.dataSize data should be got from original
receive buffer, instead of returned NvPublic.

2) NvNameSize means the size of NvName without size field.
The original code treats it to be size of NvName with size
field, so the last 2 bytes are missing.

This patch fixed problem.

Yao, Jiewen 7ae130da85 SecurityPkg: Clear AuthSession content after use.
Some commands in Tpm2CommandLib accept AuthSession
as input parameter and copy to local command buffer.
After use, this AuthSession content should be zeroed,
because there might be some secrete there.
