qemu: capabilities: Detect support for JSON args for -netdev

JSON args for -netdev were added as precursor for adding the 'dgram'
network backend type. Enable the detection and update test cases using
DO_TEST_CAPS_LATEST.

Enabling the capability also ensures that the -netdev argument is
validated against the QAPI schema of 'netdev_add' which was already
implemented but not enabled.

The parser supporting JSON was added by qemu commit f3eedcddba3 and
enabled when adding stream/dgram netdevs in commit 5166fe0ae46.
