feat(rust/driver/snowflake): add adbc_snowflake crate with Go drive…

…r wrapper (#2207)

This PR adds the `adbc_snowflake` crate to the Rust workspace. This
crate provides a Snowflake ADBC driver for Rust by wrapping the Go
driver, loaded by the Rust driver manager implementation. The `build.rs`
script builds the Go driver and links it statically.

- [x] Add methods to the wrapper structs to handle Snowflake specific
configurations
- [x] Add a feature to support loading the Go driver dynamically
- [x] Docs
- [x] Tests
