Rollup merge of #142597 - folkertdev:abi-cannot-be-called, r=workingjubilee
error on calls to ABIs that cannot be called We recently added `extern "custom"`, which cannot be called using a rust call expression. But there are more ABIs that can't be called in that way, because the call does not semantically make sense. More details are in https://github.com/rust-lang/rust/issues/140566#issuecomment-2846205457 r? `@workingjubilee` try-job: x86_64-gnu-llvm-19-3
