Process parquet bools with microkernels (#17157)
This adds support for the bool type to reading parquet microkernels. Both plain (bit-packed) and RLE-encoded bool decode is supported, using separate code paths. This PR also massively reduces boilerplate code, as most of the template info needed is already encoded in the kernel mask. Also the superfluous level_t template parameter on rle_run has been removed. And bools have been added to the parquet benchmarks. Performance: register count drops from 62 -> 56, both plain and RLE-encoded bool decoding are now 46% faster (uncompressed). Reading sample customer data shows no change. NDS tests show no change.
