Currently we require everywhere that wants to know if there
is an HPET device to check for "CONFIG_HPET || CONFIG_X_HPET_RUST".
Factor out whether the HPET device is Rust or C into a separate
Kconfig stanza, so that CONFIG_HPET means "there is an HPET",
and whether this has pulled in CONFIG_X_HPET_RUST or CONFIG_HPET_C
is something the rest of QEMU can ignore.

The configuration option of Rust HPET is missing, so that PC machine
can't boot with "hpet=on" when QEMU Rust support is enabled.
Add the Rust HPET configuration option.
