gpu: nvgpu: define EVENT_IDs in common code

All the event ids NVGPU_IOCTL_CHANNEL_EVENT_ID_* are defined in linux
specific user header uapi/linux/nvgpu.h and can't be used in common
code

Hence add new definitions of type NVGPU_EVENT_ID_* for all the events
in common code and use them wherever required in common code

For future additions to event ids, we need to update both
NVGPU_IOCTL_CHANNEL_EVENT_ID_* and NVGPU_EVENT_ID_* fields

Also add new API nvgpu_event_id_to_ioctl_channel_event_id() to convert
common event_id of the form NVGPU_EVENT_ID_* to Linux specific event_id
of the form NVGPU_IOCTL_CHANNEL_EVENT_ID_*
Use this API in gk20a_channel/tsg_event_id_post_event() to get correct
event_id
