thread-test.c: Use Windows Threading API on Windows
...When we don't have a pthreads implementation available, which is
normally the case on Windows. This attempts to make it easier for people
on Windows to verify whether their builds of Pixman (and Cairo component,
if applicable) are thread-safe. Also, make the number of threads
a #define, so if we need to change it at some point, it's easier.
This re-enables the thread-test program on Windows in Meson builds.
