[PATCH 1/4] qemu_capabilities: Add QEMU_CAPS_DISPLAY_RELOAD

[Zheng Yan]

The 'display-reload' QMP command was introduced in QEMU 6.0.0, so we
add a compatible capability to check if target QEMU binary supports it.

{"execute":"display-reload", "arguments":{"type": "vnc", "tls-certs": true}}

The new QMP refer to:
