refactor: replace pipeline::value with vrl::value
If you used greptime_identity to write positive integer data before version 0.16.0, in the following two cases:
The integer type would be recognized as u64. After version 0.16.0, however, greptime_identity will recognize this data as i64 (please note not to write data greater than i64::MAX).
This may cause a mismatch between the written data and the table schema, or an overflow leading to write failures.
You can use desc table_name to confirm the actual data type.
You can directly modify the table structure to fix this issue, or use Transform in version 2 for custom type conversion.

Process Management: Implements complete process management system with ProcessManager,
information_schema.process_list table, process killing functionality, and MySQL client
Ctrl+C support for query termination (#5865, #6309, #6320).
Bulk Insert Performance: Introducing SimpleBulkMemtable for tables without primary keys to
accelerate bulk write operations (#6054).
Partition Rule Checker: Introduces a robust point matrix-based partition rule checker that ensures completeness and uniqueness, eliminating false negatives and providing better error messages with specific uncovered/overlapped value ranges (#6431).
Pipeline Integration: Adds pipeline support for Prometheus remote write and Loki API (#5981, #6390).
VRL Processing: Introduces Vector Remap Language (VRL) processor for advanced data transformation within pipelines, allowing users to write VRL scripts for flexible data processing (#6205).
