Decouple warn error options from core and adapters

[MichelleArk]

resolves #9337

Problem

WarnErrorOptions is now defined in dbt/common, which is being moved to a separate upstream package/repo (dbt-common) shortly. It is defined in dbt/common because it is used both by dbt-common and dbt-core. Unfortunately, it depends on both dbt-core and dbt-adapter to import the event type module to validate items in its collection. This would represent a circular dependency once moved to a separate repo as dbt-common should be upstream to both dbt-adapter and dbt-core.

Solution

• update WarnErrorOptions constructor to accept valid_error_names on instantiation, for use in validation
• provide valid_error_names during WarnErrorOptions construction in dbt-core with ALL_EVENT_NAMES (combines adapter+common+core events)
• moved test_helper_types unit tests to tests/common since helper_types is defined in common and only has dbt-common dependencies!
