meson: Add support for building with precompiled headers

This substantially speeds up building for windows. A cross build with mingw
goes from

real	0m29.884s
user	15m41.900s
sys	1m58.257s

to

real	0m13.196s
user	6m52.330s
sys	1m15.140s

The wins on windows are similar-ish (but I don't have a system at hand just
now for actual numbers).
