VaM 1.x Console Application (win32) to force VAM to run on X3D cores in AMD processors

[Italian Job]

Hello, below is my contribution to the community.
It was developed for AMD processors with 16 cores, 8 of which feature X3D technology.
Embarcadero RAD C++ Builder 13 environment
This is a console application designed to force VAM to run on the CCD that houses the cores with X3D cache in AMD Processor. This is done without having to disable the second CCD and without sacrificing performance in other applications.
AMD Ryzen 9 5950X3D
AMD Ryzen 9 7950X3D
AMD Ryzen 9 9950X3D
