Make DisplayList its own type instead of an alias, pushing the Skia aspect behind it mostly. Removes a bunch of manual memory management and opens the door to DisplayList being a union type with multiple implementations Test: builds (somehow), boots, hwuiunit passes, CtsUiRendering passes Change-Id: I1d7806aa3afc5d9ece08b06959920078a5814c59
