This linthas been split up into four finer-grained lints, with`unknown_or_malformed_diagnostic_attributes` now being the lint groupthat contains these lints:  1. `unknown_diagnostic_attributes`: unknown to the current compiler  2. `misplaced_diagnostic_attributes`: placed on the wrong item3. `malformed_diagnostic_attributes`: malformed attribute syntax oroptions4. `malformed_diagnostic_format_literals`: malformed format stringliteral- [Allow constants whose final value has references to mutable/externalmemory, but reject such constants

Thisprimarily affects the use of implementing traits on an `extern "{abi}"`function pointer, like `extern "stdcall" fn()`, on a platform thatdoesn't support that, like aarch64-unknown-linux-gnu.
