## Description
Moves common code and its dependencies used by both Q35 and SBSA into a
new QEMU common package.
1. Created QemuPkg DSC, DEC, CI.yaml
2. Moved common modules from QemuQ35Pkg to QemuPkg
4. Moved common IndustryStandard, Guid headers to QemuPkg
5. Moved common PCDs to QemuPkg and moved to the QemuPkg token space
6. Added QemuPkg.dec to Q35 & SBSA dependencies, and to individual INFs
as needed.
This refactor contains no code changes aside from token space renames.
