> Implement GzipByteBuffDecompressor with off-heap decompression path

> Key: HBASE-30321

> Project: HBase
> Issue Type: Improvement

>
> Add GzipByteBuffDecompressor, a ByteBuffDecompressor implementation that
> enables GZIP decompression directly from/to ByteBuffer objects without
> intermediate byte array copies.
> one decompression path is supported:
> - Off-heap (direct ByteBuffer): delegates to Hadoop's native
> ZlibDirectDecompressor with AUTODETECT_GZIP_ZLIB when native zlib is loaded
> Also adds GzipHFileDecompressionContext to carry per-block configuration, and
> input-length validation to reject inputs too short to be a valid GZIP member.
> The prior code had no ByteBuff-based GZIP decompression path, requiring byte
> array copies for on-heap scenarios. This eliminates those copies for both
> direct and heap buffer cases.
