src: allow inspector without v8 platform

Embedders sometimes want to take control of V8 platform initialization
themselves, so we wouldn't want to experience an error if
NODE_USE_V8_PLATFORM was false necessarily. Instead, we can also gate
it with HAVE_INSPECTOR to allow embedders to define that themselves
and use Inspector without NODE_USE_V8_PLATFORM.
