Implement --setpref for xpcshell tests to change preferences
A few suites (e.g. mochitest, reftest, etc.) support `--setpref foo.bar=baz` to change a preference value in the temporary test profile. This is very useful for toggling debugging/logging prefs during test development. Currently one is require to modify files in the source directory to change preference values for debugging which is tedious and error prone (e.g. the debugging changes may accidentally get checked-in).
