K1: introduce BUILDER_INFERENCE_STUB_PARAMETER_TYPE to prevent compiler crashes

This diagnostic is reported in rare situations when
StubTypeForBuilderInference is kept as a parameter type
of for loop or lambda. Before this commit, we had in K1
"Could not load module <error module>" from IrLinker instead.
