IMPALA-7979: Enhance decoders to support value-skipping

This commit adds value-skipping functionality to the decoders.
Value-skipping is useful when we know that we won't need the
following N values, so instead of decoding and dropping them, we
can just "jump" through them.

This feature is a prerequisite for Parquet page skipping (IMPALA-5843).

I added backend tests for all the decoders.
