Feat/postgres 16 (#4761)

Browse Source 
This adds PostgreSQL 16 as a vendored postgresql version, and adapts the
code to support this version. 
The important changes to PostgreSQL 16 compared to the PostgreSQL 15
changeset include the addition of a neon_rmgr instead of altering Postgres's
original WAL format.
