Rename HWUI ATRACE memory counters

Rename HWUI ATRACE counters from "Graphics CPU Memory",
"Graphics Texture Memory" and "GPU Memory" to "HWUI CPU Memory",
"HWUI Texture Memory" and "HWUI GPU Memory". New names apply
for purgeable memory, but with "Purgeable " prefix.
Add a new counter "HWUI All Memory", which is a sum of the other 3.
New counter simplifies perfetto query needed to detect a
memory regression.
