Module diagnostics

Clippy wrappers around rustc’s diagnostic functions.

These functions are used by the INTERNAL_METADATA_COLLECTOR lint to collect the corresponding lint applicability. Please make sure that you update the LINT_EMISSION_FUNCTIONS variable in clippy_lints::utils::internal_lints::metadata_collector when a new function is added or renamed.

Thank you! ~The INTERNAL_METADATA_COLLECTOR lint
