OvmfPkg/QemuFwCfgLib: Provide Pei and Dxe specific library Current QemuFwCfgLib.inf is used in both Pei and Dxe phases. Add Pei and Dxe inf file to provide a seperate QemuFwCfgLib instances for Pei and Dxe phases.

OvmfPkg/QemuFwCfgLib: move InternalQemuFwCfgIsAvailable() to lib instances InternalQemuFwCfgIsAvailable() is an API that is incorrectly exposed by the "OvmfPkg/Include/Library/QemuFwCfgLib.h" library class header; the API is meant to be used internally to library instances (if it's needed at all). In OvmfPkg, we have two lib instances (for SEC and PEI/DXE); they provide different implementations of InternalQemuFwCfgIsAvailable(), for the shared file "OvmfPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c". Move the API declaration to a new internal header called "QemuFwCfgLibInternal.h", and drop EFIAPI in the process.

OvmfPkg: QemuFwCfgLib: extract stateful implementation The current implementation of QemuFwCfgLib is: - stateful - implicitly initialized in the library constructor. OVMF's SEC runs from read-only memory/flash. When the library is linked into a SEC binary (which currently never happens), the "mQemuFwCfgSupported" global variable becomes read-only, making the library non-functional. Extract the stateful, implicitly initialized library implementation into a separate file, making room for a stateless, explicitly queried implementation that's usable in SEC. Restrict the stateful implementation to the current, non-SEC clients.
