Bug 266244 – REGRESSION(271419@main): [GTK][WPE] Build fails if clang <= 14

• Component: New Bugs
• Status: RESOLVED FIXED

WebKitGTK and WPE are failing to build when using clang 14 after 271419@main. This changeset introduced a change that makes use of `std::views::values` in the files:
  - Source/WebCore/platform/graphics/gstreamer/mse/SourceBufferPrivateGStreamer.cpp
  - Source/WebCore/platform/graphics/gstreamer/mse/SourceBufferPrivateGStreamer.h

It seems clang-14 doesn't support `std::views:values`. Here is a small example that fails to build with clang-14:

```
#include <iostream>
#include <map>
#include <ranges>

int main() {
    std::map<int, std::string> myMap{
        {1, "one"},
        {2, "two"},
        {3, "three"}
    };

    for (const auto& value : std::views::values(myMap)) {
        std::cout << "Value: " << value << std::endl;
    }

    return 0;
}
```

Since this feature is only used in these two files in the entire WebKit codebase, I'd like to revert the changes in those two files, so WebKitGTK and WPE can still be built with clang-14.
