Log:
clang-format: [JS] prevent wraps before class members.
Summary: In JavaScript/TypeScript, class member definitions that use modifiers
can be subject to Automatic Semicolon Insertion (ASI). For example, "class X {
get \n foo }" defines a property called "get" and a property called "foo", both
with no type annotation. This change prevents wrapping after the modifier
keywords (visibility modifiers, static, get and set) to prevent accidental ASI.
