LibCore: Return ErrorOr<pid_t> and support arguments in Process::spawn

Browse source 
This makes the wrapper more like the rest in LibCore, and also
removes the annoying limitation of not supporting arguments.

There are three overloads one for String, char const *, and StringView
argument lists. As long as there are <= 10 arguments the argv list
will be allocated inline, otherwise on the heap.
