test: add variable arguments support for Argv
At the moment Argv only supports three arguments which fulfilled my requirements when working on #9163.
This commit adds support for a variable number of arguments. There is also a no-args constructor that is the equivalent to running "node -p process.version" which is hopefully alright as a default.
