REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3997
This change added an extra step to allow check for installed ACPI
tables.
For FADT, MADT, GTDT, DSDT, DBG2 and SPCR tables, either
pre-installed or
supplied through AcpiTableInfo can be accepted.
An extra check for FADT ACPI table existence during installation step is
also added.
