Add memory tracing in HWUI

Add ATRACE memory counters to track memory usage at the end
of each frame in HWUI.
There are 3 catagories: CPU, GPU and Texture memory.
There are 3 more counters for memory that can be purged.
This CL deletes GpuMemoryTracker class, which implemented
similar function for Android O HWUI renderer.

Test: Collected systrace with gmail and setting.
Test: memory tracing adds ~0.1ms per frame when ATRACE is enabled
