[PATCH] D62738: [HIP] Support texture type

This patch handles `__attribute__((device_builtin_vector_type))`  for HIP.

If a class or struct type has this attribute, any variables with this type will
be emitted as global symbol in device code with undef initializer, and
registered by `__hipRegisterVar` with shadow variable in host code.

This allows HIP runtime to implement support of HIP texture type.

For CUDA, there is no change for codegen since it depends on implementation.
