Revert "Reland cc: Decode discardable images in PaintRecord backed shaders."

This reverts commit 8fafe68a2435c9992cda9906f7fc8bd7ec7d6daa.

Reason for revert:
- `cc_unittests` MSan failure, starting in https://build.chromium.org/p/chromium.memory/builders/Linux%20MSan%20Tests/builds/4662. 

Original change's description:
> Reland cc: Decode discardable images in PaintRecord backed shaders.
> 
> This relands commit 576bda00f9ee4d41f309069b88513b34049f58ee.
> 
> For PaintRecord backed shaders, the rasterization is done internally in
> skia, which means images present in these shaders are not pre-decoded
> by compositor's decode cache. This change ensures that we capture these
> images during discardable image analysis, and replace them with decoded
> images from the compositor's cache.
> 
> Replacing of these images requires transforming the PaintRecords in
> these shaders to SkPictures with decoded images before executing the op
> with the shader.
