Jiaqi Gao 5396354b86 SecurityPkg: Add constraints on PK strength
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3293

Add constraints on the key strength of enrolled platform key(PK), which
must be greater than or equal to 2048 bit. PK key strength is required
by Intel SDL and MSFT, etc. This limitation prevents user from using
weak keys as PK.

The original code to check the certificate file type is placed in a new
function CheckX509Certificate(), which checks if the X.509 certificate
meets the requirements of encode type, RSA-Key strengh, etc.
