Split Permissions from PermissionProviders classes

[MikeAlhayek]

Permission constants should be extracted into a dedicated or a constants class but should not be part of any permission provider.

Permission provider should live into the module where the Permission constants should be in the core project.

This if we need to check for the permission constant, we don't need to reference the module.

We triaged this issue and set the milestone according to the priority we think is appropriate (see the docs on how we triage and prioritize issues).

This indicates when the core team may start working on it. However, if you'd like to contribute, we'd warmly welcome you to do that anytime. See our guide on contributions here.

I think it will be better to add the permissions in OC.XXX.Abstractions instead this will be helpful for 3rd part modules, but I agree we could add them into OC.XXX.Core where the abstractions is not exist or for modules that have core package such as Search
