Auto merge of #13210 - Alexendoo:lintcheck-force-warn, r=xFrednet

lintcheck: force warn all lints

It occurred to me that like `--filter` we could use `--force-warn` for normal operations, we especially want to see lints that crates decided were too annoying or were false positives

Also excludes `clippy::cargo` from the default set as nobody is really writing those and it slows things down

r? `@xFrednet`
