Is your feature request related to a problem? Please describe.
Some users wish to write Parquet data using the ZStandard compression codec rather than the Snappy codec. RAPIDS is unable to accelerate writing of these files due to the lack of support for this codec on Parquet writes.

Describe the solution you'd like
The libcudf Parquet writer APIs should support specifying the ZStandard codec as one of the possible compression codecs to use when encoding the Parquet data for writing.

Enable ZSTD compression in ORC and Parquet writers (#11551)
578e65f 
Closes #9058, #9056

Expands nvCOMP adapter to include ZSTD compression.
Adds centralized nvCOMP policy. `is_compression_enabled`.
Adds centralized nvCOMP alignment utility, `compress_input_alignment_bits`.
Adds centralized nvCOMP utility to get the maximum supported compression chunk size - `batched_compress_max_allowed_chunk_size`.
Encoded ORC row groups are aligned based on compression requirements.
Encoded Parquet pages are aligned based on compression requirements.
Parquet fragment size now scales with the page size to better fit the default page size with ZSTD compression.
Small refactoring around `decompress_status` for improved type safety and hopefully naming.
Replaced `snappy_compress` from the Parquet writer with the nvCOMP adapter call.
Vectors of `compression_result`s are initialized before compression to avoid issues with random chunk skipping due to uninitialized memory.
