GCC: Remove redundant group_size argument from vectorization APIs
tldr
Vectorization APIs now infer group size from statement vector length, simplifying internal data structures.

This commit removes the group_size argument from several internal vectorization helper functions (e.g., vect_build_slp_tree*). This argument was redundant because the statement vector length already implicitly provides this information. The change simplifies the internal data structures used by the vectorizer and improves code clarity.
