vulkan : fix TOP_K for +inf/NaN inputs and k = 1 on negative values (#30107) The bucket search in topk_nary_search.comp started from the range [0, 0xFF800000), which ends just below the ordered-uint mapping of +inf, so +inf and NaN were never counted. A workgroup block with fewer than k countable values left the ballot empty and the shader read uninitialized shared state (hang/device lost on NVIDIA, wrong indices on AMD), and a few +inf in a block were selected without being counted, dropping real top values. Map NaN to -inf on input, start from [0, 0xFFFFFFFF) so every value is counted, and clamp the top bucket's end (2^32) instead of wrapping to 0. The k = 1 path compared float bits as signed integers, which orders negative values backwards; compare floats instead. Add test_top_k_inf to test-backend-ops: negative values, fewer than k +inf and many -inf, for k = 1, 10, 40.
