According to the UEFI spec and commit message of "PCD switch to avoid using ACPI reclaim memory", so need to add this support in the InstallAcpiTableFromAcpiSiliconHob(). 1. Fixed memory corruption issue in the InstallAcpiTableFromAcpiSiliconHob(). 2. Added "PCD switch to avoid using ACPI reclaim memory" support in the InstallAcpiTableFromAcpiSiliconHob().

Got RSDP table which installed during the FSP phase from Hob, then pass it to the DXE AcpiTableInstance. 2. Got XSDT from RSDP and extract necessary data from XSDT, according to the old XSDT to Initialize a new XSDT. 3. Re-install ACPI table from old XSDT to the new XSDT. a. If Hob has DSDT table then re-install DSDT table in the new XSDT. If not, then skip it. b. If Hob has FACS table then re-install FACS table in the new XSDT. If not, then skip it.

This patch provides an optional method controlled by PCD to avoid using EfiACPIReclaimMemory, by setting the PCD PcdNoACPIReclaimMemory to TRUE, all ACPI allocated memory will use EfiAcpiMemoryNVS instead.
