vm: add bindings for v8::CompileFunctionInContext

[ryzokuken]

Adds a method compileFunction to the vm module, which serves as a
binding for v8::CompileFunctionInContext with appropriate args for
specifying the details, and provide params for the wrapper.

Eventually, we would be changing Module._compile to use this internally
over the standard Module.wrap
