Improve perf overlay performance. (#5571)
1. Mark perf overlay path as volatile
2. Set sample_margin_width = 0 to get a bar graph instead of saw-tooth.

Previously, the perf overlay itself could be a significant performance
hit and that makes it difficult to profile flutter app.

Flow

Flow is a simple compositor based on Skia that the Flutter engine uses to cache recoded paint commands and pixels generated from those recordings. Flow runs on the GPU thread and uploads information to the GPU.
