Before this change the check was quite complicated
because of cases like:
for (i in 1..9)
foo(i)<caret>
It's not located in a block, but in the same time it's a stament.
So we had a tricky heuristics that if is parent is not a block, then
we should check if element isn't used as expression.
Of course this heuristics is wrong, e.g. for import/package nodes.
The solution is to reuse similar logic from BasicExpressionTypingVisitor.
it has been checked once that statement container is one of:
- KtBlockExpression
- KtContainerNodeForControlStructureBody
- KtWhenEntry
So there's no need to check anything else

#KT-14483 Fixed
There is new settings checkCanBeUsedAsValue
Also expression filtering are split into to parts:
- getNonFilteredExpressions is trivially goes until it reaches
first block body of some declarations
- all additional filtering is merged into Condition that is passed into
PostfixTemplateExpressionSelectorBase super-call
Notable changes for users:
- do not suggest try for non-top-level expressions
- do not suggest var/par/etc for loops
