When compiling with MinGW, use of the __thread attribute causes pixman
to gain a dependency on the winpthread DLL.  With Autotools, this could
be avoided by configuring with ac_cv_tls=none, causing pixman to fall
back to TlsSetValue() instead.

Add a Meson 'tls' option that can be 'disabled' to skip support for TLS
compiler attributes, or 'enabled' to require a working TLS attribute.

Since aarch64 has different neon syntax from aarch32 and has no
support for (older) arm-simd,
there are no SIMD accelerations for pixman on aarch64.

We need new implementations.

This patch also contains Ben Avions's series of patches for aarch32
and now the benchmark results are fine to aarch64.

Please find the result at the below ticket.

- gtk is only used in demos
- libpng is only used in tests
- openmp is only used in tests (in the standard build)

Add option to include cpu-features.[ch] from a given path
into the build for platforms that don't provide this out
of the box. This is needed on Android.

This commit adds a meson build system for pixman. It carries the usual
improvements of meson, better clean build time, much better incremental
build times, while being simpler and easier to understand.

This takes advantage of some features from the most recent versions of
meson: the builtin openmp dependency and the feature option type.

There are a couple of things that I've done a bit differently than the
autotools build system, I've built a libdemos which is the utilities
from the demos folder, and I've linked the demos with libtestutils from
tetsts, otherwise I expect that most things will be the same.

I've tested so far cross compiling from x86_64 -> x86, x86_64 ->
Aarch64, and Linux to Windows via mingw, as well as native x86_64 Linux
builds which all work. I've also built with mingw nativly, there are
some test failures there. An MSVC build can be generated, but fails.

v2: - set WORDS_BIGENDIAN in the config for big endian systems.
