Add tidy check for rustdoc templates to ensure the whitespace characters are all stripped

Fixes rust-lang#130559.

I'm planning to send a follow-up in case a tag at the end of a line isn't needed (if the next line starts with a jinja tag for example).

[rustdoc] Remove unneeded jinja comments

This is a follow-up of rust-lang#130585.

Since we now check for the jinja comments we missed, we can now check for the jinja comments which are unneeded. It will make the parsing and therefore the compilation a tiny bit faster (well, if anyone sees a difference haha). The real goal is mostly to have easier to read template files. 😉
