Standardize DDL images to RGBA

With the following CL:

https://skia-review.googlesource.com/c/skia/+/213220 (Alter createTestingOnlyBackendTexture methods)

we lose the BGRA-ness of testingOnlyBackendTextures on desktop machines so, upon upload, the required swizzle isn't happening. This CL switches all the DDL images to RGBA to work around the problem. Once the backendTexture API settles down we will need a way to specify the format of the uploaded data separate from the format of the backendTexture.
