Adds the command: make skps_release_and_SIMD for perfing builds against a set of SKPs in ~/skps for release and simd builds of CanvasKit. Also outputs a summary of the perf results in a table format. See the document "SIMD CanvasKit Build Performance Testing" for more details: https://docs.google.com/document/d/114kdSGPMnOSQCZ7pFgd3MGMn5mIW562RMoXVmD13e0M/edit# Bug: skia:10453 Change-Id: I311629a1420301dda41f7ec57ce1403b05fd949b Reviewed-on: https://skia-review.googlesource.com/c/skia/+/301982 Reviewed-by: Elliot Evans <elliotevans@google.com> Reviewed-by: Kevin Lubick <kjlubick@google.com>
