feat(rpc): remove PageAttribution from the protocol, attribute on the client side (#2957)
This also changes timeout error format to
"page.click: Timeout 5000ms exceeded", so that all errors
can be similarly prefixed with api name.

We can now have different api names in different clients,
and our protocol is more reasonable.
