feat(sql-schema-connector): wasm-compatible sql-schema-connector

[jkomyno]

This PR:

• Closes ORM-458
• Introduces new compile-time flags in sql-schema-connector
• Leaves schema-engine-cli's functionality and the related tests (which use native Rust drivers) untouched
• Allows wasm compilation via the sqlite feature

  cargo build -p sql-schema-connector --features sqlite --target wasm32-unknown-unknown

• Allows wasm compilation via the mysql feature

  cargo build -p sql-schema-connector --features mysql --target wasm32-unknown-unknown

• Allows wasm compilation via the mssql feature

  cargo build -p sql-schema-connector --features mssql --target wasm32-unknown-unknown

• Allows wasm compilation via the postgresql feature

  cargo build -p sql-schema-connector --features postgres --target wasm32-unknown-unknown

• Allows wasm compilation via the cockroachdb feature

  cargo build -p sql-schema-connector --features cockroachdb --target wasm32-unknown-unknown

• Exposes a new constructor for external Driver Adapters, to be used in core
• Implement sql_schema_connector::flavour::SqlFlavour trait for quaint::connector::ExternalConnector wrappers:
  • sqlite: ORM-505
  • postgresql + cockroachdb: ORM-506

LGTM, one thing I am worrying about is that we might end up with drift between the driver adapters and the native driver SqlFlavour, when I look at the existing SqlFlavour for native drivers it seems we should be able to re-use most of it (but not an issue yet)
