UefiCpuPkg: VTF0 Linear-Address Translation to a 1-GByte Page till 512GB

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3473

X64 Reset Vector Code can access the memory range till 4GB using the
Linear-Address Translation to a 2-MByte Page, when user wants to use
more than 4G using 2M Page it will leads to use more number of Page
table entries. using the 1-GByte Page table user can use more than
4G Memory by reducing the page table entries using 1-GByte Page,
this patch attached can access memory range till 512GByte via Linear-
Address Translation to a 1-GByte Page.

Build Tool: if the nasm is not found it will throw Build errors like
FileNotFoundError: [WinError 2]The system cannot find the file specified
run the command wil try except block to get meaningful error message

Test Result: Tested in both Simulation environment and Hardware
both works fine without any issues.
