OvmfPkg: CloudHv: Fix FW_BASE_ADDRESS
The FW_BASE_ADDRESS value provided by OvmfPkgDefines.fdf.inc is
incorrect for the CloudHv target. We know the generated firmware
contains a PVH ELF header, meaning it will be loaded according to the
address provided through this header. And since we know this address
isn't going to change as it's part of CloudHvElfHeader.fdf.inc, we can
hardcode it through a new include file CloudHvDefines.fdf.inc, which
replaces the generic one OvmfPkgDefines.fdf.inc.
With this change, we prevent the firmware from accessing MMIO addresses
from the address range 0xffc00000-0xffffffff since we know the firmware
hasn't been loaded on this address range.

OvmfPkg: Check for QemuFwCfg availability before accessing it
There are few places in the codebase assuming QemuFwCfg will be present
and supported, which can cause some issues when trying to rely on the
QemuFwCfgLibNull implementation of QemuFwCfgLib.

OvmfPkg: CloudHv: Rely on QemuFwCfgLibNull implementation
Since Cloud Hypervisor doesn't support the fw_cfg mechanism, it's more
appropriate to rely on QemuFwCfgLibNull implementation of QemuFwCfgLib
since it provides a null implementation that will not issue any PIO
accesses to ports 0x510 and 0x511.

OvmfPkg: Don't access A20 gate register on Cloud Hypervisor
Since Cloud Hypervisor doesn't emulate an A20 gate register on I/O port
0x92, it's better to avoid accessing it when the platform is identified
as Cloud Hypervisor.
