[refurb] Implement slice-to-remove-prefix-or-suffix (FURB188)

[dylwil3]

This PR implements FURB188 which suggests the use of removeprefix/removesuffix in order to remove prefixes and suffixes from strings, rather than slicing the string conditionally upon the output of startswith/endswith.

Tested using same test suite as refurb.

Moves the needle on #1348.

[dylwil3]

Not super happy with how gnarly the implementation is - so open to any feedback/tips to clean it up. I've tried to add comments wherever possible so hopefully it is at least readable.

Definitely found myself wishing that Rust supported matching patterns involving structs with heavily nested Boxes... (rust-lang/rust#87121)

Nice! I can see that a lot of work went into this

[MichaReiser]

I only skimmed over the rust code and left a few NIT comments.

[dylwil3]

Wow @AlexWaygood and @MichaReiser - what a fantastic and thorough code review! Thanks so much! Learning a lot from you

[AlexWaygood]

Very nice indeed! Basically just nits remaining, though there is one other location where I think you should use match_builtin_expr() for correctness

[dylwil3]

Thanks again! I think I picked the remaining nits.

Fab! Some tiny last remaining comments:

Thanks!
