[RESEND PATCH v3 2/4] OvmfPkg/LockBoxLib: use PcdAcpiS3Enable to detect S3 support

["Lin, Gary (HPS OE-Linux)" <gary.lin@hpe.com>]

To avoid the potential inconsistency between PcdAcpiS3Enable and
QemuFwCfgS3Enabled(), this commit modifies LockBoxLib to detect
S3 support by PcdAcpiS3Enable as modules in MdeModulePkg do.
