fix: async arrow functions should not be allowed after binary… (#11284) 
* Forbid async arrow functions after binary operator.

This commit makes Babel throw an error when parsing
code like "3 + async() => 2".

* Make atPossibleAsync more accurate

* Change atPossibleAsync to atPossibleAsyncArrow

Add an extra test to atPossibleAsync and refactor it to
atPossibleAsyncArrow. This also fixes a bug in the Typescript plugin,
so a new test has been added.

* Add test for async arrow after unary operator
