Auto merge of #13056 - y21:rm-compiler-lint-functions, r=Manishearth

Remove internal `compiler_lint_functions` lint

This internal lint has effectively been superseded by `disallowed_methods` when we started using that in #11811 (I didn't even know that we also had this internal lint at the time of when I created that PR).

Some of the methods that this looks for also don't exist anymore (`span_lint_note` and `span_lint_help`), though there was one that that lint had but wasn't disallowed in clippy.toml (`LintContext::lint`)

changelog: none
