6901: Temp fixes panic caused by no ast for proc-macro r=maklad a=edwin0cheng

There are some panic when hover/goto definition for proc-macro. It is because in current design, we don't have `ast-node` for proc-macro and then it trigger [this](https://github.com/rust-analyzer/rust-analyzer/blob/479d1f7eec22c3564867223e2093f14774092528/crates/hir/src/has_source.rs#L116) line to panic.

This PR is a temp fix for all of these similar to https://github.com/rust-analyzer/rust-analyzer/blob/bd4c352831662762ee7a66da77ec9adf623b0a0a/crates/completion/src/render/macro_.rs#L42
