Description

Expected Behavior of the rule

When user manually adds all the usesite targets targeted by the all then we should suggest user to use all instead

Context

all meta usesite target the new experimental feature introduced in Kotlin. We can create this rule to educate users to promote the usages of all. Also it's very common usecase to annotate a ctor param will all types of usesite so that it works well with Firestore type of libs

Contributor guide

Research direction
Study existing detekt rules, especially those that check for redundant or suggested code patterns. Look at how `UseSiteTarget` annotations are parsed. Implement a rule that checks if a use site target annotation uses all individual targets that `all` would cover, and flag it to suggest using `@file:UseSiteTarget(AnnotationTarget.ALL)` instead. Write tests similar to other rule tests.
