[CUDA][HIP] Fix host/device based overload resolution

Currently clang fails to compile the following CUDA program in device compilation:

__host__ int foo(int x) {
     return 1;
}

template<class T>
__device__ __host__ int foo(T x) {
    return 2;
}

__device__ __host__ int bar() {
    return foo(1);
}

__global__ void test(int *a) {
    *a = bar();
}

This is due to foo is resolved to the __host__ foo instead of __device__ __host__ foo.
This seems to be a bug since __device__ __host__ foo is a viable callee for foo whereas
clang is unable to choose it.

This patch fixes that.
