Fix clang compilation error in PlatformXR::ViewData initialization

[Imanol Fernandez]

Compilation can fail if the related C99 extension is not supported.

Mixture of designated and non-designated initializers in the same initializer list is a C99 extension [-Wc99-designator]

../../Source/WebCore/platform/xr/openxr/PlatformXROpenXR.cpp:218:24: warning: mixture of designated and non-designated initializers in the same initializer list is a C99 extension [-Wc99-designator]
        views.append({ .active = true, Eye::Right });
                       ^~~~~~~~~~~~~~
../../Source/WebCore/platform/xr/openxr/PlatformXROpenXR.cpp:218:40: note: first non-designated initializer is here
        views.append({ .active = true, Eye::Right });
