QRhi static constants causing missing symbols

   auto &v = QRhiShaderResourceBinding::Data::MAX_TEX_SAMPLER_ARRAY_SIZE;
    qDebug() << v;

causes

main.cpp:8: error: undefined reference to `QRhiShaderResourceBinding::Data::MAX_TEX_SAMPLER_ARRAY_SIZE'

For example, the Python bindings generator generates them as public const properties and runs into this. The suggestion would be to make them typed enums.
