All instances of injecting an EE specific module have been changed to
use the new methods for this: prepend_if_ee, extend_if_ee, and
include_if_ee. This allows these lines to be included in CE, even when
the modules to inject do not exist. This in turn allows us to backport
these lines to CE and keep them there, instead of having to strip them
out.

This extends the InjectEnterpriseEditionModule RuboCop cop so that it
verifies the following:

1. The line number the injection occurs on (as before).
2. The method used (e.g. prepend instead of prepend_if_ee).
3. The argument type passed when using the new module injection methods.

This adds the methods prepend_if_ee, extend_if_ee, and include_if_ee
that can be used to inject EE specific modules in EE.

These methods are exposed as an initializer that is loaded as soon as
possible. For tests that use fast_spec_helper.rb we must load this
initializer manually, as the Rails environment is not loaded. This is
not the most pretty setup, but unfortunately there is no alternative
that we can use.

1. The output isn't great. It can be hard to find hotspots and, even
   when you do find them, to find why those are hotspots.
2. It uses some jQuery-specific frontend code which we can remove now
   that we don't have this any more.
3. It's only possible to profile the initial request, not any subsequent
   AJAX requests.
