Rename GatherDiscardableImages to better reflect functionality
This patch changes some uses of GatherDiscardableImages in the following
way:
Settings leading up to the recording part are called
"Image Decode Tasks Enabled"
At recording time, this is called
"Generate Discardable Images Metadata"
At raster time, this is called
"Get Discardable Images in Rect"
Hopefully this makes it a bit easier to navigate this part of the code.
