Enable MicrobatchConcurrency for dbt-snowflake

[MichelleArk]

As part of dbt-labs/dbt-core#10624, dbt-adapters 1.10.1 introduced a new Capability, MicrobatchConcurrency. Opting into this capability indicates to core that the adapter supports concurrent invocations.

In order for snowflake to safely support concurrent microbatch strategy runs, temp tables must be named uniquely, using the new model.batch.id context attribute, which is only available for microbatch models.
