fix missing "if" in API docs for ActionController::Parameters#permit

After merging #19377 ActionPack tests were missing a require for
`ActiveSupport::LogSubscriber::TestHelper` and change didn't take
into account that logger could be nil. Added the require and only log to
info if logger exists.

This wasn't caught earlier because these tests only run after a merge.

Fix method signature of `parse_query` to match rack

Recently rack was changed to have a second argument on the `parse_query`
method (in rack/rack#781). Rails relies on this and it's `parse_query`
method was complaining about missing the second argument. I changed the
arguments to `*` so we don't have this issue in the future.

Allow an array to be a default translation value.

4.2.1 introduced a change to the way `translate`/`t` works with an
option of `default: [[]]`. In 4.2.0, this would give a default value of
`[]`, but in 4.2.1, it leads to a missing translation.

`default: [[]]` is again allowed for cases where a default of `[]` is
needed.

This addresses GitHub issue 19640.

`sql_runtime` was getting invoked even when the logger was set to fatal.
This ensures that does not happen by checking that the logger is set to
info level before logging the view runtime.

This reduces the number of times `sql_runtime` is called for integration
tests with a fatal logger from 6 to 2.

When replacing a has_many association with the same one, there is nothing to do with database but a setter method should still return the substituted value for backward compatibility.
