[PATCH 2/6] qemu: capabilities: Introduce QEMU_CAPS_COMPAT_DEPRECATED

The capability is asserted if qemu supports the -compat deprecated-input= and deprecated-output= settings to control what should happen if deprecated fields are used in QMP. This will be used for a developer/tester-oriented setting which will aid us in catching use of deprecated settings sooner.
