test: move to app directory

Since all other apps have been moved to the "app" folder, the autotest app
remains alone in the test folder. Rather than having an entire top-level
folder for this, we can move it back to where it all started in early
versions of DPDK - the "app/" folder.

This move has a couple of advantages:
* This reduces clutter at the top level of the project, due to one less
  folder.
* It eliminates the separate build task necessary for building the
  autotests using make "make test-build" which means that developers are
  less likely to miss something in their own compilation tests
* It re-aligns the final location of the test binary in the app folder when
  building with make with it's location in the source tree.

For meson builds, the autotest app is different from the other apps in that
it needs a series of different test cases defined for it for use by "meson
test". Therefore, it does not get built as part of the main loop in the
app folder, but gets built separately at the end.
