adbc-driver-snowflake: Add version 1.11.0

[luhenry]

• Package: adbc-driver-snowflake
• Version: 1.11.0
• Source: https://github.com/apache/arrow-adbc
• Docs: https://arrow.apache.org/adbc/

Compiles the Go-based ADBC Snowflake driver (go build -buildmode=c-shared via CMake) into a py3-none wheel. Upstream publishes no riscv64 wheel.

Mirrors upstream's packaging.yml python-manylinux job, same shape as build-adbc-driver-flightsql.yml.

Differs from upstream

• Go toolchain installed in the manylinux image from go.dev - image ships none; version read from upstream's .env
• Wheel retag done inline - upstream's python_wheel_fix_tag.py is not a package file

Matrix: single cp312 build - wheel is py3-none, one wheel serves all interpreters.

Testing

• Upstream's suite needs a live Snowflake account (ADBC_SNOWFLAKE_URI) and self-skips without it
• Added an offline smoke test: loads the driver, parses a DSN, reads options back
