[CK-tile] unhardcode the number of LDS banks from universal gemm policy (#3130)

Browse Source 
Fixes LDS bank conflicts on gfx950 for universal gemm v3 pipeline

Replaces hardcoded LDS layer calculations with dynamic computation using the new architecture helpers

Adds architecture-specific helper function get_n_lds_banks()

Changes function attributes from CK_TILE_HOST_DEVICE to CK_TILE_DEVICE in universal gemm policy
