Move array test files under array
Add missing test case for Array#to_sentence, collect all test cases for Object#to_param at one place and avoid repitition
Remove @state.parent assignment on commit

This piece of code was introduced on
67d8bb963d5d51fc644d6b1ca20164efb4cee6d7 , which was calling
`committed?` in the `transaction_state` before calling the `committed!`
method. However on 7386ffc781fca07a0c656db49fdb54678caef809, the
`committed?` check was removed and replaced by a `finalized?`, which
only checks if the state is not nil. Thus we can remove that line.

eval_block should be private
only ask for the routes module once

we can cache the module on the stack, then reuse it
pass the module to define_named_route_methods

after this, we can disconnect @module from the instance
helpers should be a Set so it doesn't grow unbounded

since helpers is a set, we can be confident about when to remove methods
from the module.
ask the named routes collection if the route is defined

we should not be accessing internals to figure out if a method is
defined.
oops! :bomb:

use helpers.include? so we don't get any false positives

Closes #16343
Deprecate `*_path` methods in mailers

Email does not support relative links since there is no implicit host. Therefore all links inside of emails must be fully qualified URLs. All path helpers are now deprecated. When removed, the error will give early indication to developers to use `*_url` methods instead.

Currently if a developer uses a `*_path` helper, their tests and `mail_view` will not catch the mistake. The only way to see the error is by sending emails in production. Preventing sending out emails with non-working path's is the desired end goal of this PR.

Currently path helpers are mixed-in to controllers (the ActionMailer::Base acts as a controller). All `*_url` and `*_path` helpers are made available through the same module. This PR separates this behavior into two modules so we can extend the `*_path` methods to add a Deprecation to them. Once deprecated we can use this same area to raise a NoMethodError and add an informative message directing the developer to use `*_url` instead.

The module with warnings is only mixed in when a controller returns false from the newly added `supports_relative_path?`.
