Improves API clarity by making the property name match the excludePackages and excludeTypes pattern. Also removes unnecessary dependsOn from computeAdviceTask - the type usage task should only run when explicitly invoked, not as part of buildHealth.

Please provide guidance here - I've added this, but I'm not sure what should actually be included here.

Curious if we should provide certain defaults here for exclusion out of the report

Should we include usedAnnotationClasses ?

Summary
A new task to build type usage report (#1637).
Introducing a new
ComputeTypeUsageTasktask. It generatestype-usage.jsonreporting which types (classes) your code uses from each dependency. Designed for analyzing module dependency usage and complexity.{ "projectPath": ":app", "summary": { "totalTypes": 245, "totalFiles": 67, "internalTypes": 12, "projectDependencies": 3, "libraryDependencies": 18 }, "internal": { "com.example.MyClass": 5 }, "projectDependencies": { ":core": { "com.example.core.Utils": 2 } }, "libraryDependencies": { "org.apache.commons:commons-collections4": { "org.apache.commons.collections4.bag.HashBag": 3 } } }Usage:
