bitpacking is not using SIMD

[sunchao]

What is the problem the feature request solves?

It seems bitpacking is not levering SIMD at the moment. We probably need to use explicit SIMD to enable it. We can also check the version in arrow-rs and see if it already supports it.

Describe the potential solution

Leverage SIMD for bitpacking, which is used in several hot paths in Parquet read.

Closed as we no longer have a Parquet reader in Comet after #4363, instead delegating to arrow-rs.
