Clarify log_softmax benchmark defaults

Document the rank-dependent compatibility default dimension separately from
Paddle's native axis default, and keep the package metadata consistent.

# Add compatible `log_softmax` public APIs

Implement `log_softmax` so that Paddle's standard and compatibility-facing public APIs expose consistent behavior without regressing the existing operator.

compatibility-facing public APIs 是啥意思

Comment thread swe-paddle/tasks/PaddlePaddle__Paddle-78220/instruction.md
- `paddle.special.log_softmax`
- `paddle.compat.nn.functional.log_softmax`

When the dimension is explicitly specified with equivalent `axis`/`dim` values, all five routes must produce numerically equivalent results. The routes do not need to produce the same result when the dimension is omitted: `paddle.nn.functional.log_softmax` keeps Paddle's default `axis=-1`, while the compatibility-style routes use the PyTorch-compatible `dim=None` rule, which selects a dimension based on the input rank.

while the compatibility-style routes use...

compatibility-style routes 是指 paddle.compat.nn.functional.log_softmax 么
