Move ICH to rustc_query_system

Based on https://github.com/rust-lang/rust/pull/89183

The StableHashingContext does not need to be in rustc_middle.

This PR moves it to rustc_query_system. This will avoid a dependency between rustc_ast_lowering and rustc_middle in https://github.com/rust-lang/rust/pull/89124.
