Create package name consistency rule

[xgouchet]

What does this PR do?

This PR include a new Detekt rule enforcing our package naming policy:

• A top level named declaration (ie: (enum|data|sealed)? class, object, interface, fun, val|var) which is marked as internal must be in a package matching /**.internal.**/
• A top level named declaration (ie: (enum|data|sealed)? class, object, interface, fun, val|var) which is not marked as internal must not be in a package matching /**.internal.**/
• this rule ignores issues on annotated declarations
