eal: add cache line demotion API

rte_cldemote is similar to a prefetch hint - in reverse.
On x86, cldemote(addr) enables software to hint to hardware that line is
likely to be shared. This is quite useful in core-to-core communications
where cache-line is likely to be shared.
ARM and PPC implementation is provided with NOP and can be added if any
equivalent instructions could be used for implementation on those
architectures.

eal: add new prefetch write variants

This commit adds new rte_prefetchX_write() variants, that suggest to the
compiler to use a prefetch instruction with intention to write. As a
compiler builtin, the compiler can choose based on compilation target
what the best implementation for this instruction is.

Three versions are provided, targeting the different levels of cache.

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.
