gnu: pixman: Update to 0.46.4.

Upstream no longer uses autotools so we build with meon-build-system now.  The
configure flag to not build a static output is no longer supported and even
though it was used previously, there was still a static library built.
Finally, the gnuplot configure flag is also removed, per
<https://issues.guix.gnu.org/69962>.

* gnu/packages/xdisorg.scm (pixman): Update to 0.46.4.
[build-system]: Switch to meson-build-system.
[arguments]<#:configure-flags>: Rewrite with gexp and for meson.  Remove
"--disable-static" as it is not a supported flag.  Remove "--enable-gnuplot"
flag.
[inputs, native-inputs]: Remove.
[home-page]: Use https URL.
