iio: Add event enums for running period and count
There are devices (such as Murata IRS-D200 PIR proximity sensor) that
check the data signal with a running period. I.e. for a specified time,
they count the number of conditions that have occurred, and then signal
if that is more than a specified amount.
`IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is
therefore not suitable for these devices. Add a new `iio_event_info`
`IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also
add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the
number of conditions that must occur during this running period.
