[meta-oe][RFC PATCH] include-what-you-use: new recipe

[Christian Eggers <ceggers@arri.de>]

Based on proposal send previously here:
https://lists.yoctoproject.org/g/yocto/topic/recipe_for/83279588

This recipe depends on meta-clang, so should it be added to that layer?

Unfortunately the 'include-what-you-use' (iwyu) tool doesn't work yet.
Although I have installed nativesdk-clang (via CLANGSDK = "1") and
nativesdk-include-what-you-use packages, the C++ standard headers are
not found:

include-what-you-use --sysroot=/opt/poky/5.0.2/sysroots/cortexa7t2hf-neon-vfpv4-poky-linux-musleabi impl/Fdt.cpp
impl/Fdt.cpp:9:10: fatal error: 'cerrno' file not found
    9 | #include <cerrno>
      |          ^~~~~~~~

As iwyu uses Clang and I have no experience working with it, this is
probably only a beginner mistake. Can Clang use the C++ headers provided
by libstdc++, or do I need to install further packages?
