[RFC PATCH 3/8] qemu: Add capability detection for ACPI EGM memory device
Add QEMU capability detection for the ACPI EGM memory device feature.
This allows libvirt to determine if the QEMU binary supports the
required functionality before attempting to use it.
The capability is exposed through the QEMU device type 'acpi-egm-memory'
and is used to validate device configuration and command line generation.
