Add Crc32ieee()/crc64() Support #7480 (azat Khuzhin)

Add CRC32IEEE()/CRC64() support #7480 (Azat Khuzhin)
Added support for CRC32IEEE() and CRC64() functions for computing CRC checksums in ClickHouse.

Why it matters

These functions provide users with efficient methods to calculate CRC32 and CRC64 checksums which are commonly used for error-checking and data integrity verification. This feature enhances ClickHouse's capability to handle checksum computations natively within SQL queries.

How to use it

Use the functions CRC32IEEE() and CRC64() directly in your SQL queries to compute CRC32 and CRC64 checksums respectively. For example:

SELECT CRC32IEEE(your_column) FROM your_table;
SELECT CRC64(your_column) FROM your_table;
