gpu: nvgpu: Remove circular dependency in PMU includes

Remove including gk20a.h from pmu_gk20a.h. This causes a fallout
as some #includes were missing.

gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the
include.

Including mm_gk20a.h in gr_gp10b.h causes recursive include, as
mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to
remove the dependency.

gr_ctx_gk20a.h used struct gk20a pointers, but did not forward
declare it. Add a forward declaration.

gr_gk20a.h uses dbg_session_gk20a, but was missing forward
declaration.

gr_gk20a.h did not include nvgpu.h but it uses preemption types from
that header. Add include.
