Introduce a build flag "RT_DEBUG" to enable runtime debug, so that we can have a handy method for UEFI runtime services debug.
This build flag only applies to DEBUG build; the reason for not enabling it for DEBUG build by default is that we are still using the same UART of OS and it may cause potential conflict. User needs to specify "-D RT_DEBUG=TRUE"; "-D RT_DEBUG" is not enough for we use !if $(RT_DEBUG)==TRUE in the code.
