Reland [HIP] fix host min/max in header (#133590) CUDA defines min/max functions for host in global namespace. HIP header needs to define them too to be compatible. Currently only min/max(int, int) is defined. This causes wrong result for arguments that are out of range for int. This patch defines host min/max functions to be compatible with CUDA. Since some HIP apps defined min/max functions by themselves, newly added min/max function are under the control of macro `__HIP_DEFINE_EXTENDED_HOST_MIN_MAX__`, which is 0 by default. In the future, this will change to 1 by default after most existing HIP apps adopt this change. Also allows users to define `__HIP_NO_HOST_MIN_MAX_IN_GLOBAL_NAMESPACE__` to disable host max/min in global namespace. min/max functions with mixed signed/unsigned integer parameters are not defined unless `__HIP_DEFINE_MIXED_HOST_MIN_MAX__` is defined. Fixes: SWDEV-446564
