    www/qt5-webengine: fix build with clang 21

    With libc++ 21 www/qt5-webengine fails to build, with errors similar to:

        In file included from
gen/third_party/blink/renderer/platform/platform_jumbo_54.cc:7:
       
./../../../../kde-qtwebengine-5.15.19p0/src/3rdparty/chromium/third_party/blink/renderer/platform/image-encoders/image_encoder_utils.cc:63:5:
error: static assertion expression is not an integral constant expression
        [...]
       
../../../../kde-qtwebengine-5.15.19p0/src/3rdparty/chromium/base/metrics/histogram_macros_internal.h:45:12:

enumeration type 'RequestedImageMimeType'
           45 |     return static_cast<Enum>(

https://chromium.googlesource.com/chromium/src/+/bb340f66aaf44206fa5106509fb4e8c0719ee831
    fixes these, but has to be slightly adjusted to make it apply to the
    specific chromium version included in qt5-webengine.
