tests : speed up tensor data generation and model saving (#31145)

• tests : speed up tensor data generation and model saving

Refactor save_models to create only the model, not a llama_context,
which is not needed for saving. Replace the slow std::normal_distribution
draw with a splitmix64 + box-muller normal generator.

• tests : use a shared pool of normal draws for tensor data

Generate a pool of normal draws once with std::mt19937 and
std::normal_distribution, then have every tensor copy a cyclic slice of
it instead of running a per-tensor box-muller. The name-keyed slice
selection keeps the draw deterministic.

• tests : log the size of saved models

Report the produced file size in bytes and MB after each save.

• tests : simplify the model save log

Put the model name, target and size on one line per saved model.
