qemu: capabilities: Introduce QEMU_CAPS_MACHINE_HPET capability

The capability represents that qemu accepts the configuration of the
HPET timer via -machine hpet=on/off rather than the
soon-to-be-deprecated '-no-hpet' option.

The capability is detected from 'query-command-line-options' which
recently added the 'hpet' option.
