Alex Chi Z 6921577cec compute_ctl: grant default privileges on table to neon_superuser (#6845)
## Problem

fix https://github.com/neondatabase/neon/issues/6236 again

## Summary of changes

This pull request adds a setup command in compute spec to modify default
privileges of public schema to have full permission on table/sequence
for neon_superuser. If an extension upgrades to superuser during
creation, the tables/sequences they create in the public schema will be
automatically granted to neon_superuser.

Questions:
* does it impose any security flaws? public schema should be fine...
* for all extensions that create tables in schemas other than public, we
will need to manually handle them (e.g., pg_anon).
* we can modify some extensions to remove their superuser requirement in
the future.
* we may contribute to Postgres to allow for the creation of extensions
with a specific user in the future.
