Reusing opaque rust type across bridges in same file

[NikolaBo]

I am following #942 to reuse an opaque rust type across cxx bridges by manually implementing ExternType. I found that if the two cxx bridges are in the same file it fails.

  error[cxxbridge]: the name `Process` is defined multiple times
     ┌─ src/main.rs:34:9
     │
  34 │         type Process = crate::handle::Process;
     │         ^^^^^^^^^^^^ the name `Process` is defined multiple times

However, if i move one of the modules containing a bridge to another file it works.

Here is an example of the issue, and the same bridges working when separated to different files.

We have a solution internally and a RFC and a PR open here (#1187) since months.

Unfortunately, there is absolutely no feedback by the crate owner on the PRs and RFCs here (we have a lot of advanced functionality already used in our project, but I can't get it upstreamed w/o owner's review).
