Utils: Make process results accessible through QtcProcess object

The result is fully stored in the object anyway. Using the extra
SynchronousProcessResponse structure only causes copies of
the data and complicates access on the user side in
a lot of cases.

The result bits are now also accessible individually.

There's obvious room for follow-up changes on the topic, e.g.
ShellCommand::runCommand's parameter list could shrink to
just a SynchronousProcess parameter.
