Jonah Williams effea219cb [Impeller] dont cache glyph layout if atlas is invalid. (flutter/engine#56879)
Fixes https://github.com/flutter/flutter/issues/159578

When the screen is shut off, the atlas context is destroyed but the text frames are not. This can lead to a state where we expect the glyph atlas to be populated but it is not. make sure to check if the atlas itself is valid.
