Chase Latta dfb009d70a [fuchsia] allow injecting the inspect node
This CL allows users to inject the inspect node used inside the
os_fuchsia.cc file instead of having it get created automatically.
This allows us to use inspect in other areas of the flutter/dart
runners. This code needs to be soft transitioned so there will be
follow up CLs after the runners are migrated.

TEST=This was tested against the current version of the runner that does
not use these new codepaths and against a version that does.
