Make aliases of `database` option in generators work

Thor automatically adds `-` if aliases do not start with `-`.
https://github.com/erikhuda/thor/blob/0879c1773d188902d54f95174f33961ac33111f8/lib/thor/parser/options.rb#L53

But Thor follows a convention of one-dash-one-letter options.
So, even if `-` is added to `db`, it does not work.

Fix database configuration when adding another config level

roflscaling (using frozen string constants instead of literal
strings) was added in 2012, before frozen string literals were
added in Ruby 2.3.  Now that Rails no longer supports Ruby <2.3,
and all of these files use frozen string literals, there is
no reason to keep the roflscaling.

This does not delete or deprecate the related constants. Such
a change can be made in a later commit.

This also prevents insert_all from leaking its attributes checks.

`values_list` is quite long and does far too many things. This also
eagerly extract the keys in initialize instead of having to worry about
calling them multiple times.

This is kind of hard to explain but if you have a database config with
another level like this:

```
development:
  primary:
    database: "my db"
    variables:
      statement_timeout: 1000
```

the database configurations code would chooke on the `variables` level
because it didn't know what to do with it.

We'd see the following error:

```
lib/active_record/database_configurations.rb:72:in
`block in find_db_config': undefined method `env_name' for [nil]:Array
(NoMethodError)
```

The problem here is that Rails does correctly identify this as not a
real configuration but returns `[nil]` along with the others. We need to
make sure to flatten the array and remove all the `nil`'s before
returning the `configurations` objects.

Fixes #35646

Probably that is useful for any other feature as well.

Internal usage for the method as public has removed at #29623.

In #10634 the behavior of Time#advance was changed to maintain a
proleptic gregorian calendar for dates before calendar reform. However
it didn't full address dates a long time before calendar reform and
they gradually drift away from the proleptic calendar the further you
go back in time. Fix this by always converting the date to gregorian
before calling advance which sets the reform date to -infinity.
