Add many, many missing types to PostgresDataType

[gwynne]

IMPORTANT: This PR only deals with defining the well-known OIDs for Postgres built-in types. Except for adding more array/element type mappings, it does NOT add any additional support for any of these types, not even basic encoding and decoding! That support will be a separate PR.

Including but not limited to:

• Several geometry types (lseg, path, box, polygon, line)
• The reg* types (regclass, regtype, etc.)
• Missing network address types (macaddr8, inet, cidr)
• Array types for both existing and other new types
• bit and bit varying
• The pseudo-types (cstring, internal, any, anycompatible, etc.)
• The text search types (tsvector, tsquery)
• Missing range types (numrange, tsrange, tstzrange, daterange)
• jsonpath
• The multirange types (int4multirange, nummultirange, etc.)
• Some special-purpose types (tid, xid, cid, xid8, pg_lsn, trigger, etc.)

Also adds full two-way mappings for every known array type (including existing ones that were missing the mapping, like money).

Requires minor version bump (adds new public API and deprecates PostgresDataType.pgNodeTree)

Can we add a comment where the source of truth is?

Can we add a comment where the source of truth is?

The source of truth I used is the actual pg_type table in a fresh database as it appears in my installation of Postgres 15, with a bunch of "really internal" types removed by eye; there's not really any one place to point for truth other than the Postgres docs.
