Refactor property calls in reflection, fix some corner cases

- compute a FunctionCaller instance for getter and setter so that "call" only
  delegates to that FunctionCaller's "call", in the same way it's done in
  KFunctionImpl
- use RuntimeTypeMapper.mapPropertySignature to get the exact origin and
  signature of a property and its accessors. This makes unwrapFakeOverride call
  unnecessary and also fixes some cases like private Java fields
- temporarily drop custom range checks, will be re-added soon
