Jan Wassenberg 2ebbe4076f 1.03-1.08x decode speedup: precompute Rope theta, fuse
Split attention into functions, move into class.
Fuse Rope and MulBy, allow non-in-place version to avoid copy from q to KV.
Sink if() into MaybeLogitsSoftCap.

Jan Wassenberg 5e433e774a 1.1x prefill speedup, revamp threading in preparation for hierarchical parallelism.
Limit thread counts to detected. Add max_clusters arg.
Update detection logic to check for smt0 - previously we pinned to some siblings.

Jan Wassenberg aaf51898b6 Major revamp #2 of Prefill: fix token order, parallel for multi-query
- Allocate only the required KV caches and activation batch size
- Add flags for batch sizes
- Const-correct interface: Span of const int.
- Also clean up the KVCache arg to a span.
- Move kPrefillBatchSize into RuntimeConfig and remove related global constants.

Jan Wassenberg 09a7e75ead Prep for sharding gemma.cc: split into kv_cache, tokenizer.
Move activations.h to backprop/ to make space for another activations.h.

Jan Wassenberg 3e2396f98c Use Loader/AppArgs to construct gemma_test model, simplify AcceptFunc
accept_token: allow default, check if empty when using
allow mixing sample_func and stream_func, call the latter after the former
Also fix missing includes/deps.

Zoltan Szabadka a3a75b77f9 Use CompressedWeights<TConfig<float>> in backpropagation.
kWeightsAreCompressed are removed and LoadRawWeights is moved
to compress_weights.cc

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 465998d25a Add support for custom sampling function to runtime config.
With this addition the ComputeCrossEntropy function can be moved
to its own library, because now we can compute it using only the
public API functions from gemma.h
