SecurityPkg/Tcg2Smm: Measure the table before patch.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1940
According to TCG PFP specification: the ACPI table must be
measured prior to any modification, and the measurement
must be same cross every boot cycle.
There is a fix 3a63c17ebc853cbb27d190729d01e27f68e65b94
for the HID data. However that is not enough.
The LAML/LASA and PCD configuration change may also cause
similar problem.
We need measure the table before any update.
