Merge pull request #17310 from souris-dev/cunion-docs
Added C unions to interoperability docs
[contributed by @souris-dev; reviewed by me]
Added examples about C unions in the interoperability docs. Fixes #17294.
[editor's note: This is pretty cool: We've had the ability to interoperate with C unions
for quite some time without necessarily realizing it]
