Consolidate database specific JSON types to `Type::Json`

Fix `default_scoped` with defined `default_scope` on STI model

Should use `quote` for a string literal

Follow up of #29077.

Before:

```sql
SELECT sql FROM sqlite_master WHERE tbl_name NOT IN ("foo") ORDER BY tbl_name, type DESC, name
```

After:

```sql
SELECT sql FROM sqlite_master WHERE tbl_name NOT IN ('foo') ORDER BY tbl_name, type DESC, name
```

> If a keyword in double quotes (ex: "key" or "glob") is used in a
context where it cannot be resolved to an identifier but where a string
literal is allowed, then the token is understood to be a string literal
instead of an identifier.

We don't get any benefit from it at all.

Extract `NumericData` model for tests

Add missing `delegate :extending, to: :all`

This regression is caused by d1249c1a.

If STI model is defined `default_scope`, `base_rel` is not respected.
I fixed to merge `base_rel` in that case.

Support PostgreSQL 10 `pg_sequence`

Another fix for #28780 based on discussions at #28789

- In PostgreSQL 10 each sequence does not know its `min_value`.
A new system catalog `pg_sequence` shows it as `seqmin`.
Refer https://github.com/postgres/postgres/commit/1753b1b027035029c2a2a1649065762fafbf63f3

- `setval` 3rd argument needs to set to `false` only when the table has no rows
to avoid `nextval(<sequence_name>)` returns `2` where `1` is expected.

- `min_value` is only necessary when the table has no rows. It used to be necessary
since the 3rd argument of `setval` is always `false`.

Remove requirement on mathn

Replace therubyracer with mini_racer

The test using mathn was first introduced in f1d91790 to check that the
`distance_of_time_in_words` properly doesn't use the `Fixnum#/` method
by explicitly requiring this library as it redefines this method.

Given that `mathn` has been gemified in Ruby 2.5 and is deprecated since
version 2.2, we can certainly safely assume that people will most-likely
not require this library in their application.

However, to make sure that we don't regress, let's add a test similar to
the one before f1d91790.

The assert_same above obviously guarantees this will pass, but this
seems less likely to be deleted just because the implementation changed.
