At this point we're ready to retire QemuFwCfgS3Enabled() from the QemuFwCfgLib class, together with its implementations in:
- ArmVirtPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c - OvmfPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c Extend all modules that call the function with a new QemuFwCfgS3Lib class dependency. Thanks to the previously added library class, instances, and class resolutions, we can do this switch now as tightly as possible.
