Marcin Mikosik 9fd6ada970 [java] IDEA-283208 Add quickfix: Lift 'throw' out of 'switch' expression

Adds a quick-fix: "Lift 'throw' out of 'switch' expression" that that is provided for error "'switch' expression does not have any result expressions".
Some rare cases are not handled (fix is not provided for mentioned error).
For example when switch is used inside:
 - initialization/condition/update part of for loop
 - initializer of class field
 - condition of do-while loop
 - lock expression in synchronized statement
 - any part of assert statement
 - resource initializer of 'try' statement
