fix spacing in generated code

[z80dev]

tldr: rustfmt doesn't handle stuff inside annotations well so we manually patch some spacing issues, mainly turning account stuff like this:

# [account (init , space = std :: mem :: size_of :: < dot :: program :: Calculator > () + 8 , payer = owner , seeds = ["Calculator" . as_bytes () . as_ref () , owner . key () . as_ref ()] , bump)]

into

#[account(init, space = std::mem::size_of::<dot::program::Calculator>() + 8, payer = owner, seeds = ["Calculator".as_bytes().as_ref(), owner.key().as_ref()], bump)]

Also, convert /// CHECK comments back to that format

Overall goal is to make the generated source easier to examine and more familiar by sticking to what Anchor usually looks like

Thanks for this! I'm a bit hesitant about adding our own formatting stuff instead of just throwing it to rustfmt. Is rustfmt not formatting the current output sensibly?

unfortunately not. what rustfmt gets is a stream of tokens which lack whitespace info, and rusfmt produces really ugly output in annotations specifically
