Tagir Valeev 6fe2638869 [java] IDEA-257411 Update pattern matching for instanceof support for Java 16

1. Do not report error if non-final variable is reassigned
2. Report error in Java 15 if 'final' modifier is used
3. Allow specifying 'final' modifier on introduce variable
4. Support non-final variables in PatternVariableCanBeUsed inspection
5. Copy modifiers in PatternVariableCanBeUsed quick-fix
