CockroachDB relies on each node's tzinfo data for resolving named timezones like America/New_York and for applying daylight-savings rules. This can lead to inconsistent results across a cluster when coercing date/time strings into temporal types.

The desired solution is to store tzinfo data as a system table, to be bootstrapped and maintained by a tzinfo distribution baked into the cockroach binary.

This would also make it easier to implement #31710 to support (custom) timezone abbreviations.
