[CUDA] Fix NumericLimits

[tianleiwu]

Description

• Fix NumericLimits<float> that used infinity as max, which is not consistent with std::numeric_limits<float>::max()
  In Windows, (float)(1e+300) is used for INFINITY, which causes compiler error in Visual Studio 2022 v17.12 Preview 5.
• Rename NumericLimits<T>::Min to Lowest to be consistent with std::numeric_limits
• Fix topk implementation: use NumericLimits<CudaT> instead of NumericLimits<T> in kernel. That could avoid defining a confusing defintion of NumericLimits<MLFloat16> that returns half instead of MLFloat16.
• Use CUDART_MAX_NORMAL_FP16 if possible. It sets bits value directly, which is faster than converting float to half.

Note that NumericLimits does not support __nv_bfloat16 and _nv_fp8_e4m3 and __nv_fp8_e5m2 right now.
