uapi: habanalabs: add gaudi2 defines

Add the new defines for GAUDI2 uapi interface.

It includes the following:
1. Enums of engines and PLLs.
2. New information in the info IOCTL that is retrieved by the driver.
3. Update comments regarding the CB/CS/wait for CS ioctls.
4. New fields in the debug IOCTL for configuring the profiler for
   Gaudi2.

There is no new IOCTL.

Some of the changes are also relevant for Greco (which will be
upstreamed later this year). When ever it says "Greco and onwards",
it means it is also for Gaudi2.
