added `--verbose` option to zenserver-test and `xmake test` (#798)

* when `--verbose` is specified to zenserver-test, all child process output (typically, zenserver instances) is piped through to stdout. you can also pass `--verbose` to `xmake test` to accomplish the same thing.
* this PR also consolidates all test runner `main` function logic (such as from zencore-test, zenhttp-test etc) into central implementation in zencore for consistency and ease of maintenance
* also added extended utf8-tests including a fix to `Utf8ToWide()`
