Jan Wassenberg f9b390b134 Support all weight types in a single binary.
This changes the command line flags, but the default value retains the previous behavior.

Also add a CreateGemma helper to enable extra args without interface changes.

Zoltan Szabadka 36e4d8bbfe Add first version of backpropagation support.
This is still in progress / experimental, currently it is only
implemented for normal gemma MQA attention layers, and no
parallelism is added yet for backward pass.

Since we need to remember all activations from all layers, the
forward pass was also reimplemented with a new activation data
structure.
