Fixes https://github.com/dart-lang/linter/issues/3046
The diff looks bigger than it is. The gist is:
* There is a check for if the ParenthesizedExpression is immediately
wrapped with parens. Move that check higher.
* There are broad exceptions for ConditionalExpressions and
TypeLiterals being wrapped with parens. Also move those higher.
* Add allowances for wrapped expressions which "directly" contain
whitespace, except for a few cases where the parens are still
considered unnecessary, such as an expression that is an argument.
* Add allowances for PrefixExpressions and PostfixExpressions which
are the "targets" of property access or method invocations.
