OvmfPkg/XenAcpiPlatformDxe: remove QEMU fw_cfg dependency

Browse Source 
The QemuDetected() function wraps QemuFwCfgIsAvailable(); it always fails
on Xen. Because of that, we can eliminate the QemuDetected() call itself
from the Xen ACPI platform driver, and then the rest of "Qemu.c" becomes
useless -- the workhorse function of that source file is
QemuInstallAcpiTable(), which we no longer call.

Remove any dependencies that are no longer needed by the
XenAcpiPlatformDxe driver.
