Brandon DeRosier c43fb87612 [Impeller] Comprehensively label snapshots (flutter/engine#41325) ...

Makes it much easier to work out where things are going wrong in filter
chains.

For example, when capturing the app in
https://github.com/flutter/flutter/issues/124956, the chain of
RenderPasses gets labeled as follows:
1. Contents to ForegroundPorterDuffBlend Filter Snapshot
2. Contents to GaussianBlur Filter Snapshot
3. Directional Gaussian Blur Filter
4. Directional Gaussian Blur Filter

...and so it's easy to see that the filter chain is
ForegroundPorterDuffBlend->DirectionalGaussianBlur->DirectionalGaussianBlur,
and the former two are triggering a non-collapsed snapshot of their
inputs.
