Fix multiline lambda expression statement formating (#8466)

## Summary

This PR fixes a bug in our formatter where a multiline lambda expression
statement was formatted over multiple lines without adding parentheses.

The PR "fixes" the problem by not splitting the lambda parameters if it
is not parenthesized

## Test Plan

Added test
