Devin Ragotzy 723f515b60 Add macro_braces lint to check for irregular brace use in certain macros
Rename unconventional -> nonstandard, add config field

Add standard_macro_braces fields so users can specify macro names and
brace combinations to lint for in the clippy.toml file.

Fix errors caused by nonstandard_macro_braces in other lint tests

Fix users ability to override the default nonstandard macro braces

Add type position macros impl `check_ty`
