fix(script/spawn): calucate the correct cycles_base

[mohanson]

What problem does this PR solve?

Problem Summary:

When current_cycles is called in spawn, only the sum of the cycles of the parent script and the current script is returned, and the grandpa script is not included.

What is changed and how it works?

What's Changed:

Add a cycles_base parameter to spawn. Make child script's cycles_base equal to parent script's cycles_base + parent script's machine.cycles()
