gpu: nvgpu: set aggressive_sync_destroy at runtime

Browse Source 
We currently set "aggressive_destroy" flag to destroy
sync object statically and for each sync object

Move this flag to per-platform structure so that it
can be set per-platform for all the sync objects

Also, set the default value of this flag as "false"
and set it to "true" once we have more than 64
channels in use
