validate_* session settings

These settings are available in system.settings and are autogenerated from the ClickHouse snapshot.

validate_enum_literals_in_operators

If enabled, validate enum literals in operators like IN, NOT IN, ==, != against the enum type and throw an exception if the literal is not a valid enum value.

validate_polygons

Enables or disables throwing an exception in the pointInPolygon function, if the polygon is self-intersecting or self-tangent.

Possible values:

• 0 — Throwing an exception is disabled. pointInPolygon accepts invalid polygons and returns possibly incorrect results for them.
• 1 — Throwing an exception is enabled.
