Merge #6350
6350: Make IncorrectDiagnostic match rustc by copying rustc's code. r=popzxc a=ArifRoktim
This closes #6343 and closes #6345.
The old algorithm which used a `DetectedCase` enum, didn't match how rustc thinks of cases. Some inputs can be interpreted as more than 1 case depending on the situation. For example, to rustc:
- `ABCD`: Can be both camel case and upper snake case
- `X86_64`: Can be both camel case and upper snake case
I could've made `detect_case` return a collection of `DetectedCase` and then modified the other code as such, but I think using the same code rustc uses is simpler and a surefire way to achieve the same diagnostics as rustc.
