If possible, can you land this for me?

Description:
Make v8 snapshot public in component build.

This was already public in a non-component build. This means that targets
dependent on the "v8" target can take the results of the snapshot as inputs.

This also renames the component mode checking from keying off of the
component_mode string to checking the is_component_build flag, which is now the
recommended way to do this check.
