This upgrades clang/llvm from 22.1.8 to 23.1.0 and fixes the fallout
found while testing the result.

The carried LLVM patch stack goes from 41 to 35: seven dropped
because 23.1.0 already contains the fix or the code they patched no
longer exists, three reworked for LLVM 23, and one added for a 32-bit
x86 build break, already merged in llvm-project.

Please apply with git am --keep-cr: patch 8 fixes an ovmf file that
uses CRLF line endings, and plain git am corrupts the patch.

I have also reported the underlying bugs upstream:
llvm float16 fix, merged:
https://github.com/llvm/llvm-project/pull/219675
ovmf fix, sent to edk2:
https://github.com/tianocore/edk2/pull/13038
pango warning, the root cause is in GLib, reported to both:
https://gitlab.gnome.org/GNOME/glib/-/issues/4038
https://gitlab.gnome.org/GNOME/pango/-/issues/900
vulkan-samples warning, which is a real bug in their code:
https://github.com/KhronosGroup/Vulkan-Samples/issues/1570

Tested: oe-selftest clang suites on qemuarm, qemuarm64, qemux86,
qemux86-64 and qemuriscv64 on the autobuilder, musl images on qemux86
and qemuarm64, a qemux86 world build with TOOLCHAIN=clang, 32-bit
multilib, and core-image-minimal testimage runs.
