Hi. Ray
Based on Dov Murik Comments to take the python script
changes separately,
I have filed the Bugzilla for that separately.
https://bugzilla.tianocore.org/show_bug.cgi?id=3506
verified the binary. More details are in Bugzilla.

OVMF's ResetVector is including the UefiCpuPkg's ResetVector. So, OVMF owners
please do evaluate the impact.
I think this change assumes platform owner knows which format of page table
should be chosen in build time.

I don't
This change generates the reset vector binary which only contains 1G page
table. If a platform doesn't support 1G page table, this will cause system hang.
To Ard and Jordan,
Can you evaluate whether this change impacts OVMF?
To Prince,
Can you evaluate whether this change impacts
