Robert Phillips 2c21a11923 Remove uses of SkCanvas::flush
afaict the perf surprises associated with:

https://skia-review.googlesource.com/c/skia/+/334417 (Remove SkBaseDevice::flush)

were bc Ganesh resolves MSAA buffers for SkCanvas::flush but doesn't do so for GrDirectContext::flush.

Where possible this CL switches SkCanvas::flush to SkSurface::flush (which will also resolve MSAA buffers) so that when https://skia-review.googlesource.com/c/skia/+/334417 relands there should not be any performance surprises.
