Fix `enum_variants` FP on prefixes that are not camel-case

closes #8090

Fix FP on `enum_variants` when prefixes are only a substring of a camel-case word. Also adds some util helpers on `str_utils` to help parsing camel-case strings.

This changes how the lint behaves:

1. previously if the Prefix is only a length of 1, it's going to get ignored, i.e. these were previously ignored and now is warned
```rust
enum Foo {
    cFoo,
    cBar,
    cBaz,
}

enum Something {
    CCall,
    CCreate,
    CCryogenize,
}
```

2. non-ascii characters that doesn't have casing will not be split,
```rust
enum NonCaps {
    PrefixXXX,
    PrefixTea,
    PrefixCake,
}
```
will be considered as `PrefixXXX`, `Prefix`, `Prefix`, so this won't lint as opposed to fired previously.

changelog: [`enum_variant_names`] Fix FP when first prefix are only a substring of a camel-case word.
