Merge 261530 "Update chromoting host icons"

> Update chromoting host icons
> 
> Update the host icons to the new style which includes the Chrome logo.
> This affects all chromoting components, including the Android app and
> the webapp.
> 
> All icons are based off the 512x512 PNG in the linked bug.
> 
> The smaller sizes were generated with ImageMagick, for example:
> convert chromoting512.png -resize 48x48 chromoting48.png
> 
> ICO file was generated with:
> convert chromoting16.png chromoting32.png chromoting48.png chromoting.ico
> 
> WebP versions were generated using cwebp:
> for i in chromoting*.png; do \
>   cwebp -lossless -q 100 -m 6 $i -o ${i%.png}.webp; done
> 
> Android empty_host_list icon was made by cropping 512x512 to 510x510,
> then shrinking by a factor of 3, then converting to grayscale, then
> darkening the image using GIMP and cropping to a few-pixels-wide
> margin.
> 
> All PNGs were optimized by running:
> tools/resources/optimize-png-files.sh -o2 remoting/resources
