The copyengine code to do big transfers or memsets supports a 64-bit
size. Each copy is done as a rectangle with either side being at most
2GB, so a size that does not align nicely is split into multiple ops. It
turns out that there are at most two of these ops, so structure the code
to not loop but do two ops explicitly.
The first copyengine operation works with the first chunk that is less
than two gigabytes long. That leaves the remaining size to be a multiple
of two gigabytes, so it's sufficient to do just another operation as a
2D rectangle whose width is two gigabytes; the remaining size determines
the height, i.e. the number of two-gig lines.
The loop did just this already, but now with at most two operations per
submit the required pushbuf length is seen more easily from the code.

Implement empty stubs of the channel watchdog functions for when
watchdog is disabled from build. Add some forward declarations that were
missing. Now most call sites don't need #idefs for the build flag.
Add error checks for the wdt alloc failure.

CE app functionality from nvgpu is non-safe for igpu. CE engines init
/reset/cg related functionality is required in safety. Hence move the
CE app logic under CONFIG_NVGPU_DGPU flag and update the sources
accordingly.
