  [SPIR-V] Preserve pointer-to-pointer element type for T*& parameters (#203113)

SPIR-V backend was collapsing T*& reference parameters down to T*,
dropping a level of indirection during element-type deduction. This
patch keeps the pointer-to-pointer level intact, fixing it both within a
function (a T** reloaded from its alloca) and across calls via
cross-function parameter propagation.

Fixes HeCBench/topk on HIP.
