Add spacing information to delimiters. This is an extension of the previous commit. It means the output of something like this: ``` stringify!(let a: Vec<u32> = vec![];) ``` goes from this: ``` let a: Vec<u32> = vec![] ; ``` With this PR, it now produces this string: ``` let a: Vec<u32> = vec![]; ```

PRINT-BANG INPUT (DISPLAY): { #![rustc_dummy] let a = "hello".len(); matches!(a, 5); }
Don't insert spaces before most semicolons in `print_tts`. This gives better output for code produced by proc macros.

PRINT-BANG DEEP-RE-COLLECTED (DISPLAY): { #! [rustc_dummy] let a = "hello".len(); matches! (a, 5); }
Remove some unncessary spaces from pretty-printed tokenstream output In addition to making the output look nicer for all crates, this also aligns the pretty-printing output with what the `rental` crate expects. This will allow us to eventually disable a backwards-compat hack in a follow-up PR.
