The new registry caching in place for registry.fd.o can not handle layers
bigger than 5 GB. The last layer we used to build on windows was 5.2 GB,
meaning that the upload would fail.
Split the layers by calling multiple `RUN`, hoping that the size will be
roughly split between those steps if we have a special layer for VS2019.
