allow unsafe and ref in grammar
#943
Conversation
`unsafe` and ref returns are allowed for delegates, local functions, and methods. Update the grammar for that part. Fixes dotnet#886 See dotnet#941 (review)
This change from dotnet#941 should be made in 7.3

I think this works, but @Nigel-Ecma may well have a nicer way of representing it. It would be nice to avoid all the branching - if we had a rule of "return_type or ref_kind + ref_return_type" then we could remove some duplication. We'd need to explicitly prohibit async ref local functions (rather than doing it in the grammar) but this wouldn't be the first time we did that sort of thing.
