gpu: nvgpu: Remove buffer_attrs struct

Browse Source 
Remove the buffer_attrs struct and replace it with a more
streamlined nvgpu_ctag_buffer_info struct. This struct allows
several different fields to all be passed by pointer to the
various kind/compression functions in the VM map process.

This path also moves several comptag/kind related functions
to the core vm.c code since these functions can be reused by
other OSes.
