Full Bit Transpose Variant for T64 Codec

Full bit transpose variant for T64 codec. Could lead to better compression with zstd. #5742 (Artem Zuikov)
Introduces a full bit transpose variant for the T64 codec, enhancing the compression efficiency when used with zstd.

Why it matters

This feature aims to improve compression ratios by applying a full bit transpose transformation within the T64 codec. It particularly benefits users relying on zstd compression by potentially achieving better space savings and faster decompression times.

How to use it

Users can enable this feature by selecting the T64 codec with the full bit transpose variant applied in their compression settings when using zstd. The specific configuration depends on how the codec is specified in their ClickHouse queries or table definitions.
