OvmfPkg/XenAcpiPlatformDxe: remove QEMU fw_cfg dependency
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.
