[IR] Use erased types in backing field initializer in case of generic delegated property

- Since neither IrProperty nor IrField is Type Parameter container
 using of proprty's type parameter in IrField related code leads to
 creation of "hanging" type parameters which should be considered as
 incorrect IR.
 - Such code designed to be prohibited in LV 1.5
 - The fix makes use of erased type in such case
 where type parameter is expected.
