DO NOT MERGE Prevent ImageWallpaper from crashing due to wide gamut

Browse Source 
ImageWallpaper may fail at either uploading texture or computing the
histogram of the bitmap, we catch the unexpected exceptions to avoid
crashing the whole process. In addition, we also take wide gamut into
account while computing the histogram.

Bug: 156087409
Test: Set 1.jpg of #34 in the bug as wallpaper.
Test: The symptom should not happen.
