submodules: update clippy and rls

Fixes clippy toolstate

Changes:
````
Update to latest compiletest-rs release
add testcase for #3462
deps: bump rustc_tools_util version from 0.1.0 to 0.1.1 just in case...
rustc_tool_utils: fix failure to create proper non-repo version string when used in crates on crates.io, bump version
UI test cleanup: Extract ifs_same_cond tests
UI test cleanup: Extract for_kv_map lint tests
Fix test for #57250
Limit infinite_iter collect() check to known types
Some improvements to util documentation
Use hashset for name blacklist
Reformat random_state tests
Use node_id_to_type_opt instead of node_it_to_type in random_state
Check pattern equality while checking declaration equality
random_state lint
Use an FxHashSet for valid idents in documentation lint
Fix suggestion for unnecessary_ref lint
Update CONTRIBUTING.md for rustfix tests
Update .fixed files via update-references.sh
Run rustfix on first UI test
Use WIP branch for compiletest_rs
````

Also updates RLS and removes the patching of rustc_tool_utils from cargo.toml

RLS changes:
````
update clippy hash and rustc_tools_util and use rustc_tools_util from crates.io
Work around #55937
Update Clippy... again
