Implement C and Java generation support for implicit/explicit operators
Fixes https://github.com/mono/Embeddinator-4000/issues/581.
@tritao is this work unfinished? I think the Windows build is basically timing out on the Run-C-Tests Cake target.
The work should be finished, I left it unmerged because I did not figure out why the Windows CI was not working and did not want to break anything.
Hey @akoeplinger - Why was this re-tagged for review? Do you want it to go in or was it a misclick?
My information, which may be out dated, was that the C backend was maintained by someone on the mono side who's since moved on.
While those of us who did Obj-C/Java could look at it, there may not be a perfect content expert to review.
master was renamed to main, @chamons you can ignore if you like.
