[dev.regabi] test: add a test for inlining closures

Add a test case for issue 43818. We don't want to mark as inlinable a
function with a closure that has an operation (such as OSELRECV2) that
we don't currently support for exporting. This test case fails to
compile without the fix for #43818.

Updates #43818
