qdev: Introduce lost tick policy property
Potentially tick-generating timer devices will gain a common property:
lock_tick_policy. It allows to encode 4 different ways how to deal with
tick events the guest did not process in time:
discard - ignore lost ticks (e.g. if the guest compensates for them
already)
delay - replay all lost ticks in a row once the guest accepts them
again
merge - if multiple ticks are lost, all of them are merged into one
which is replayed once the guest accepts it again
slew - lost ticks are gradually replayed at a higher frequency than
the original tick
Not all timer device will need to support all modes. However, all need
to accept the configuration via this common property.
