Remove all 'fresh' related code from the DI and DIInterface

[dschissler]

Hello!

• Type: code quality

• Link to issue: This is a continuation of a larger effort to clean up the DI. This related to a few recently merged PRs:

• PR 13846

• PR 13854

In raising this pull request, I confirm the following (please check boxes):

• I have read and understood the Contributing Guidelines?
• I have checked that another pull request for this purpose does not exist.
• This PR deletes a public function in the DI which is no longer used internally within Phalcon. Its possible that some third party code could rely on this in a plugin but I seriously doubt it. Hopefully this is just dead code YAY! After the Dispatcher is refactored according to the commented notes within that class then the creation of some new tests will need to be evaluated.

Through the PR mentioned in the top portion of this PR I have set the stage for this "was fresh" code to be removed. This also tightens up the DI interface. After I or someone else refactors the Dispatcher base class then its likely that some new clever tests will need to be created. For the moment this is just the next step in cleaning up the code quality and API.
