Max Podkorytov bce6ec11cd Optimize tensor descriptor functor template instantiation
Replace inline lambdas with named functor structs in transform_tensor_descriptor
to reduce template instantiation overhead and improve compile times.

Changes:
- Add three named functors in tensor_descriptor.hpp:
  - convert_visible_to_hidden_id: maps visible dimension ID to hidden ID
  - convert_visible_ids_to_hidden_ids: maps sequence of visible IDs to hidden IDs
  - generate_arithmetic_sequence_from_scan: generates consecutive hidden dim ID ranges

- Add utility functions in sequence_helper.hpp and tuple_helper.hpp:
  - unpack_and_merge_sequences(): unpacks tuple of sequences and merges them
  - generate_identity_sequences(): creates Tuple<Sequence<0>, Sequence<1>, ...>

- Update 14 call sites across threadwise transfer, wrapper, and device files
  to use generate_identity_sequences() instead of generate_tuple with lambdas

- Add comprehensive unit tests:
  - unit_sequence_helper.cpp: tests for new utility functions
  - unit_tensor_descriptor_functors.cpp: tests for new functors
