Add check for possible CStr literals in pre-2021

Fixes [](https://github.com/rust-lang/rust/issues/118654)

Adds information to errors caused by possible CStr literals in pre-2021.

The lexer separates `c"str"` into two tokens if the edition is less than 2021, which later causes an error when parsing. This error now has a more helpful message that directs them to information about editions. However, the user might also have written `c "str"` in a later edition, so to not confuse people who _are_ using a recent edition, I also added a note about whitespace.

We could probably figure out exactly which scenario has been encountered by examining spans and editions, but I figured it would be better not to overcomplicate the creation of the error too much.

This is my first code PR and I tried to follow existing conventions as much as possible, but I probably missed something, so let me know!
