OvmfPkg: QemuFwCfgLib: introduce InternalQemuFwCfgIsAvailable()
This internal function allows separation of library-internal and
for-clients external availability of fw_cfg.
The interface contract of QemuFwCfgIsAvailable() is changed so that now it
may modify fw_cfg state. All current users are compliant with the new
contract.
