K2: Fix internal error in FIR2IR caused by PCLA + String interpolation

There's an implicit contract in PCLA that the statement-level call
should be postponed iff it has something to be postponed inside.

And that contract didn't work well for string interpolation containing
some postponed calls.

Thus, we haven't run a completion results writing for them properly,
thus leaving type parameters (K from synthetic call) for expression
types instead of an inferred substituted type.

In this commit, the contract was reversed to explicitly enumerate
the cases when it's safe to resolve the candidate outside PCLA session.

See the comments at `mightBeAnalyzedAndCompletedIndependently`.
