[PATCH] contrib/plugins: add meson build file

[Anton Kochkov]

Add crossplatform Meson file to build TCG plugins since
the Makefile makes wrong assumptions about it being used only
on Linux. Tested on Linux and macOS.

I think you should go the whole hog and remove the existing makefile
machinery. Otherwise it will be confusing to users who add new plugins
to the contrib directory.

Can the overall QEMU meson invoke this directly or will it get confused
by it being a separate project?
