Support ion_stat

ion/ion_stat is the new tracepoint tracking ion buffer allocations for 4.19+ kernels.
It deprecates ion_heap_grow / ion_heap_shrink.

This change ensures the existing metrics work for the ion_stat events.
Given we no longer support the specific heap name, we use 'all' as the placeholder
