Bob Nystrom 08c38f92cb feat: allow implicit null return when return statement has no value ...

In the compiler, when a `return` token is followed by a newline or right brace, emit CODE_NULL instead of parsing an expression. This enables bare `return` statements to implicitly return null. Also removes a stale TODO comment about setter parameters and fixes a typo in a comment in wren_core.c. Adds three test cases: one for explicit return in a function, one for bare return before a brace, and one for bare return before a newline.
