drivers: sensor: mcux qdec add filter parameters

Add optional filter value properties. The filter is disabled by default
but can be enabled by setting the filter-sample-period > 0 in the dts
file. A latency is introduced if the filter is enabled. The latency can
be printed by setting sensor log level to debug.
