[webgpu] Propagate rotary_interleaved parameter to GQA shader

[xenova]

Description

This PR fixes the last tests that were failing in #26715 (comment), where rotary_interleaved=1 in GQA kernel. The root cause was that the rotary_interleaved parameter was not being propagated correctly, meaning it always defaulted to 0 in FusedQKRotaryEmbeddingProgram.
