With skia-review.googlesource.com/c/skia/+/363782, both cpu and gpu backends would gracefully fail readPixel requests where dst row bytes wasn't a multiple of dst bpp. It also updated the cpu backend's writePixels behavior to gracefully reject writePixels requests where the src row bytes wasn't a multiple of src bpp. GPU writePixels would not detect this and later trigger an assert in debug builds in GrConvertPixels (caught by the linked fuzzer bug). This adds tests to mirror the read pixels bad-row-bytes tests and updates GrSurfaceContext::writePixels to check src row bytes vs. bpp. I confirmed it fixes the fuzzer crash.
