fix(es/fixer): Fix a bug with awaited arrow fn expression

[rtsao]

Description:

The minifier currently produces invalid syntax for awaited arrow expressions, for example:

await (() => { console.log("foo") });

is minified into the following invalid syntax (missing wrapping parens):

await ()=>{ console.log("foo"); };

It's better to handle this in fixer instead of codegen.

This should be fixed in fixer.

See https://github.com/swc-project/swc/blob/963ac9efb23d4613932bcb6a29b94b9ac5d13860/crates/swc_ecma_transforms_base/src/fixer.rs
