feat: support the wan22's dit and tp parallel.

[ethan686]

including three changes, dit transformer impl, tp parallel for dit model and all the model args changes for wan2.2. Note: use mindiesd's tensor as dit's input, no tp, 10 transformer layer, the cos similarity is 100% match with mindiesd.

Code Review

This pull request implements the Wan 2.2 DiT model, introducing the transformer architecture and expanding model arguments to support VAE and DiT parameters. It also refactors DiTParallelLinear to include Megatron-style tensor parallelism. Reviewer feedback highlights multiple style guide violations, such as the requirement for explicit constructors, final class markers, fixed-width integers, and specific naming conventions for enums and parameters. Additionally, the reviewer identified a redundant semicolon and noted that structs containing member functions must be converted to classes.
