The mock process runner used in most of the tests had poor handling of
stdout/stderr:
- By default it would return the `List<int>` output from the mock
process, which was never correct since the parent process runner
interface always sets encodings, thus the `dynamic` should always be
of type `String`
- The process for setting output on a `MockProcess` was awkward, since
it was based on a `Stream<Lint<int>>`, even though in every case what
we actually want to do is just set the full output to a string.
- A hack was at some point added (presumably due to the above issues)
to bypass that flow at the process runner level, and instead return a
`String` set there. That meant there were two ways of setting output
(one of which that only worked for one of the ways of running
processes)
- That hack wasn't updated when the ability to return multiple mock
processes instead of a single global mock process was added, so the
API was even more confusing, and there was no way to set different
output for different processes.
This changes the test APIs so that:
- `MockProcess` takes stdout and stderr as strings, and internally
manages converting them to a `Stream<List<int>>`.
- `RecordingProcessRunner` correctly decodes and returns the output
streams when constructing a process result.
It also removes the resultStdout and resultStderr hacks, as well as the
legacy `processToReturn` API, and converts all uses to the new
structure, which is both simpler to use, and clearly associates output
with specific processes.
