Add RPC to enumerate contract methods

No description provided.

@vgrichina We need to expose some view call method that would describe the contract first. Then we can just return this to the nearlib. It's possible we don't even need to implement any RPC changes

[vgrichina]

@evgenykuzyakov yeah, I think we only need compiler and bindgen changes. On nearcore side we might need some changes to enforce annotations though (e.g. if we want to mark methods than can spend money).

Should be part of #3 work

What should the return format be? @vgrichina @evgenykuzyakov
