Jonah Williams 1322186f32 [Impeller] add a per-frame trace event for heap usage on Vulkan. (flutter/engine#51246)
Part of https://github.com/flutter/flutter/issues/144617

Adds MemoryBudgetUsageMB which includes the MB of VMA allocated GPU and host memory, approximately per frame. This will be recorded in the devicelab and used to track how much memory pressure we're creating.

Split out from https://github.com/flutter/engine/pull/51187 since that was reverted (and doing big changes is a bad idea anyway).
