pixman: update to 0.43.2

[bgilbert]

Marking draft for now, in hope of clarification on whether this is a stable release.

[bgilbert]

No official clarification from upstream, either in the issue or a mailing list thread. However, releases with odd minor numbers automatically enable some debug code which claims to have performance consequences, so it seems safest to treat this as a development release and not package it.

I'll leave this PR open as documentation unless wrapdb maintainers would prefer otherwise.

Bumped to 0.43.2. Per this PR, odd minors are no longer development releases, and the corresponding debug code has been removed.

This should be ready for review.

pixman| Project name: pixman
pixman| Project version: 0.43.2
pixman| DEPRECATION: None of the values ['gnu99'] are supported by the c compiler.
pixman| However, the deprecated gnu99 std currently falls back to c99.
pixman| This will be an error in the future.
pixman| If the project supports both GNU and MSVC compilers, a value such as
pixman| "c_std=gnu11,c11" specifies that GNU is prefered but it can safely fallback to plain c11.

wrapdb CI is going to see that failure a lot, I think. c_std=gnu11,c11 requires Meson ≥ 1.3.0, and many projects may want to continue supporting older Meson.

wonder if it's possible for CI to fail for wraps that have custom meson.build files only.
