[java] Improve parentheses fixer in complete statement action

1. Do not add parentheses left to caret
2. Use LongRangeSet to add parentheses at valid overload positions
3. Support vararg methods
4. Filter by outer method call arguments range
5. Do not try to fix anything in already valid inner calls

Fixes IDEA-264821 Complete current statement: wrong choice for missing bracket
