Migrate numeric types into pgrx::num

Moves `AnyNumeric`, `Numeric`, and their numeric_support module out of
`pgrx::datum` into a new top-level `pgrx::num` module (with the support
code at `pgrx::num::support`). Everything remains accessible from the
previous paths via re-export, including the `pgrx::datum::numeric` and
`pgrx::datum::numeric_support` module paths, so this is purely
organizational with no end-user impact except new path options.

Part of #2194.
