Update cspell.json files with more words and better regexps

* Add some more words to the word lists
* Ignore anything that looks like a crate path in rust
* Ignore everything that looks like a color encoding (AARRGGBB and
  similar strings)
* Change regexp about `#[cfg...]` and `#[repr...]` in rust: Require
  a word boundary (space/opening parens/whatever) after the string.
* Ignore `Qt_...` in rust.
