[MENFORCER-490] Declare enforcer-rules dependencies

[elharo]

This fixes the last easy dep declarations in this project. There are still a couple of issues that might point to bugs in the dependency analyzer. In particular, adding the dependency on javax.annotation:javax.annotation-api as done here results in an unused declared dependency warning, but taking it out results in a used undeclared dependency warning.

[slawekjaranowski]

so what is the true about: javax.annotation:javax.annotation-api is it used in project?

If is not used I would to not add only to have analyzer happy

[elharo]

It is certainly used. I'm not sure why the dependency analyzer reports it as both used and unused. Likely a bug there I need to investigate:

$ grep -R "import javax.annotation" .
./enforcer-api/src/main/java/org/apache/maven/enforcer/rule/api/EnforcerRuleHelper.java:import javax.annotation.Nonnull;
./enforcer-api/src/main/java/org/apache/maven/enforcer/rule/api/EnforcerRule.java:import javax.annotation.Nonnull;
./enforcer-api/src/main/java/org/apache/maven/enforcer/rule/api/EnforcerRule.java:import javax.annotation.Nullable;
./maven-enforcer-plugin/src/main/java/org/apache/maven/plugins/enforcer/internal/EnforcerRuleCache.java:import javax.annotation.PreDestroy;
