gccrs: Remove param_use_canonical_types checks ported from c++ front-end
We are not fully setting TYPE_CANONICAL yet but we don't need to be as
strict as the C++ front-end yet. param_use_canonical_types is a command
line option we are not using either.
gcc/rust/ChangeLog:
* backend/rust-tree.cc (comptypes): Remove some C++ specific checks in
Rust const folder for now.
