port to Rust to leverage deterministic simulating testing

[hasyimibhar]

After some consideration, I've decided to port pg2iceberg to Rust specifically to leverage deterministic simulating testing (DST). This is crucial to ensure that pg2iceberg data mirroring is correct. The architecture remains the same, but there are breaking changes due to interface differences (it's not 1.0.0 yet, so it's fine).

E2E tests are copied almost verbatim, with few additional changes:

• Test 5 includes time data type, it was missing
• Test 5 is switched to DuckDB instead of ClickHouse, because ClickHouse has a bug where uuid type is queried in the wrong byte ordering (should be fixed in 26.4). Pre-Rust port, pg2iceberg did not use uuid type, it uses string instead because I didn't know Iceberg has native uuid type.
• Added test 40 for testing support for new Postgres partitions while streaming

pg2iceberg also depends on forked iceberg-rust due to missing features upstream (only 4 commits): https://github.com/polynya-dev/iceberg-rust/tree/polynya-patches
