Removing unnecessary parenthesis (#156928)

This is simply removing unnecessary parenthesis from various places. This change is because of a change to the unnecessary_parentesis lint that will trigger there. Here is the CL https://dart-review.googlesource.com/c/sdk/+/390161.

- https://github.com/dart-lang/linter/issues/4996

If anything else is needed please let me know. 

I'd like to ask for this PR to wait a bit until the bots are run again on that CL so that I can be sure nothing else will trigger, I will come back here and update this whenever everything is complete. Thanks!
