Introduce a Gin class instead of using global functions to control gin

The Gin class holds and controls a v8::Isolate. The isolate is not
entered by default, i.e. before you can use gin for a given Gin
instance, you need to enter the isolate first, e.g. by using a
v8::Isolate::Scope.

This has the advantage that we don't rely on the deprecate default
isolate, and also support having multiple isolates in one process.

TEST=gin_unittests and mojo_js_bindings_unittests pass
