Rollup merge of #139345 - smoelius:into-iter-stability, r=lcnr

Extend `QueryStability` to handle `IntoIterator` implementations

This PR extends the `rustc::potential_query_instability` lint to check values passed as `IntoIterator` implementations.

Full disclosure: I want the lint to warn about this line (please see #138871 for why): https://github.com/rust-lang/rust/blob/aa8f0fd7163a2f23aa958faed30c9c2b77b934a5/src/librustdoc/json/mod.rs#L261

However, the lint warns about several other lines as well.

Final note: the functions `get_callee_generic_args_and_args` and `get_input_traits_and_projections` were copied directly from [Clippy's source code](https://github.com/rust-lang/rust/blob/4fd8c04da0674af2c51310c9982370bfadfa1b98/src/tools/clippy/clippy_lints/src/methods/unnecessary_to_owned.rs#L445-L496).
