Show reason for failed rename refactoring
Return an error with a meaningful message for requests to
`textDocument/rename` if the operation cannot be performed.
Pass errors raised by rename handling code to the LSP runtime.
As a consequence, the VS Code client shows and logs the request
as if a server-side programming error occured.
Resolves https://github.com/rust-analyzer/rust-analyzer/issues/3981
