RFR: 8322920: Some ProcessTools.execute* functions are declared to throw Throwable [v2]

[Stefan Karlsson]

> Most functions in ProcessTools are declared to throw Exceptions, or one of its subclasses. However, there are a small number of functions that are unnecessarily declared to throw Throwable instead of Exception. I propose that we change them to also be declared to throw Exception.
> 
> This is a trivial patch to make it easier to refactor tests to use the updated functions.
> 
> Tested manually, but will wait for GHA to verify that the change is OK.
