chore: update rust to 1.88.0

[kpop-dfinity]

Changes

1. Removed long deprecated rls component, since it's been removed from rust in 1.87.0
2. disabled uninlined_format_args check - otherwise I would have to change essentially every file in the repo in this PR... - note that the lint has been moved back to pedantic in the cargo clippy, so the problem will eventually go away, but it is still an issue in this version of rust (1.88.0). See also uninlined_format_args should have stayed in pedantic rust-lang/rust-clippy#15151
3. Explicitly ignored result_large_err warnings - I'll leave it up to the code owners whether/how to fix the warnings
4. Modified the backtrace message in rs/execution_environment/tests/backtraces.rs
5. Bumped max compressed wasm size of some nns canisters from 1.5MB to 1.6MB in file_size_check tests
6. Fixed io_other_error warnings
7. Fixed iter_kv_map warnings
8. Fixed manual_contains warnings
9. Fixed some other, rarely occurring, clippy warnings

Thanks a lot, @kpop-dfinity, the FI changes LGTM! The overview table of canbench changes is very helpful!

No canister behavior changes.

I would have probably added an explicit comment whenever added #[allow(clippy::result_large_err)], but I'm almost the last to approve, so won't block on that.

LGTM for Utopia
