[CUDA][HIP] Do not emit type info when compiling for device

CUDA/HIP does not support RTTI on device side, therefore there
is no point of emitting type info when compiling for device.

Emitting type info for device not only clutters the IR with useless
global variables, but also causes undefined symbol at linking
since vtable for cxxabiv1::class_type_info has external linkage.
