KT-16436 Incorrect primitive constants handling

Expression '1.unaryMinus()' is resolved as Int::unaryMinus call with Int receiver.
However, this expression is implicitly coerced to a different integral type (Byte, Short, Long)
based on results of constant evaluation.

Introduce IMPLICIT_INTEGER_COERCION type operator to handle such cases.

TODO: should we use it for simple constant expressions like '1' and '-1'?
