- isFunctionType -> change the only usage in TracingStrategyForInvoke to check
for exact function type
- isExtensionFunctionType -> change all usages to check for exact extension
function type because extension function types are uninheritable in Kotlin
- isExactFunctionType -> isNonExtensionFunctionType
- isExactExtensionFunctionType -> isExtensionFunctionType
- isExactFunctionOrExtensionFunctionType -> isFunctionType
- isFunctionOrExtensionFunctionType -> isFunctionTypeOrSubtype
