[cfile] KUDU-2852 Push predicate evaluation for int type RLE decoder
This change adds optimization that evaluates the predicate for each run
instead of materializing each cell and then applying the predicate
for integer datatype RLE decoder.
Tests:
- Extended all_types-scan-correctness-test with repeating
data instead of sequential to better test data encoded
with RLE.
- Verified all unit tests pass.
- TODO: Run benchmark to confirm/measure performance gains.
