deprecate invalid_ref lint
This fixes the `invalid_ref` lint test to no longer fail when https://github.com/rust-lang/rust/pull/63346/ lands. I also fixed the lint itself, because its wording made no sense: there is no "reference to zeroed/uninitialized memory" here.

Add run-rustfix for needless_bool lint
This splits up the needless_bool tests into `fixable.rs` and
`simple.rs`. `simple.rs` contains the code that triggers the lint
diagnostic without a suggestion.

cc #3630
Don't emit enum_variant_names if remainder starts with a numeric
changelog: Fix false positive in `pub_enum_variant_names` and `enum_variant_names`
As [per the reference](https://doc.rust-lang.org/reference/identifiers.html), identifiers must start with a letter. So we don't suggest a better
variant naming in case the remainder would start with a numeric.
