Initial separation of Snowflake_Dialect from Postgres_Dialect (#10266) 
- Part of #9486
- Building on top of initial work by @jdunkerley and finishing it
- Reverted the changes to the Postgres_Dialect from last Snowflake work and split the Snowflake_Dialect into a separate module.
- Moved from `rounding_decimal_places_not_allowed_for_floats` to `supports_float_round_decimal_places` (as too confusing).
- Added Snowflake_Dialect type.
- Extracted `Snowflake_Spec` into separate `Snowflake_Tests`
- It imports the common tests from `Table_Tests`.
- Some initial adaptations to make the snowflake dialect not-crash.
- Adding `Internals_Access` proxy to allow external implementations to access our internal data structures without directly exposing them to users. Users should not use these.
- Adding profiling of SQL to check performance.

This is a set of tests for the Snowflake integration for Enso.

Testing Snowflake

To run the tests, you need to prepare credentials for a Snowflake instance that can be used to run them on.

Please set the following environment variables:

  • ENSO_SNOWFLAKE_ACCOUNT - the account name for the Snowflake instance,
  • ENSO_SNOWFLAKE_USER - the username to use for the tests,
  • ENSO_SNOWFLAKE_PASSWORD - the password for the user, for security reasons this can be a plain text value or an Enso Secret. If using a secret, please provide it as path - enso://orgid/path/foo.secret,
  • ENSO_SNOWFLAKE_DATABASE - the name of the database to use for the tests,
  • ENSO_SNOWFLAKE_SCHEMA - the name of the schema to use for the tests, (optional, defaults to PUBLIC),
  • ENSO_SNOWFLAKE_WAREHOUSE - the name of the warehouse to use for the tests (optional, defaults to blank value).
