Jonah Williams 1579900629 [Impeller] leave glyph atlas in transfer dst to improve vulkan throughput. (flutter/engine#52908) 
On the vulkan backend everytime we blit a glyph we go shader read -> transfer dst -> shader read. This is pretty inefficient if we're appending many glyphs. 

Poke a hole in the blitpass API so we can leave the glyph atlas in transfer_dst to reduce the number of layout transitions.
