KON-681 Add isGeneric for declarations in declaration site

[nataliapeterwas]

This PR improves the isGeneric functionality to encompass not only use-site declarations but also declaration-site declarations in Kotlin. Previously, isGeneric was primarily applicable to use-site declarations, such as parent declarations and types. However, the need for extending this functionality to other declaration types, including classes, interfaces, type aliases, properties, and functions, has been recognized.

Enhancements Overview

1. Classes:

   Konsist code

   val isGeneric = scope
   	.classes()
   	.first()
   	.isGeneric

   • Example 1 (isGeneric Returns true):

     class GenericClass<T>(val value: T)

   • Example 2 (isGeneric Returns false):

     class NonGenericClass(val value: String)

2. Interfaces:

   Konsist code

   val isGeneric = scope
   	.interfaces()
   	.first()
   	.isGeneric

   • Example 1 (isGeneric Returns true):

     interface GenericInterface<T> {
         fun doSomething(value: T)
     }

   • Example 2 (isGeneric Returns false):

     interface NonGenericInterface {
         fun doSomething()
     }

3. Type Aliases:

   Konsist code

   val isGeneric = scope
   	.typeAliases
   	.first()
   	.isGeneric

   • Example 1 (isGeneric Returns true):

     typealias GenericTypeAlias<T, V> = (T, V) -> Unit

   • Example 2 (isGeneric Returns false):

     typealias NonGenericType = List<String>

4. Properties:

   Konsist code

   val isGeneric = scope
   	.properties()
   	.first()
   	.isGeneric

   • Example 1 (isGeneric Returns true):

     val <T> List<T>.property: T
     	get() = first()

   • Example 2 (isGeneric Returns false):

     val property: String = "Non-generic"

5. Functions:

   Konsist code

   val isGeneric = scope
   	.functions()
   	.first()
   	.isGeneric

   • Example 1 (isGeneric Returns true):

     fun <T> genericFunction(param: T): T {
         return param
     }

   • Example 2 (isGeneric Returns false):

     fun nonGenericFunction(param: String): String {
         return param
     }
