Rendered RFC

This RFC proposes to extend the Wasmtime API to allow users to define host
functions in a Config that can be shared between multiple engines and
therefore stores.

Today, Func is used to define host functions, but it is tied to a Store.
If users desire short-lived stores to ensure short-lived instances, host
functions need to be redefined upon every module instantiation.

By defining host functions with a Config, instances can be created
without having to redefine the host functions; this will make for faster module
instantiations in scenarios where a module is repeatedly instantiated.
