Subject: [PATCH] Twenty Seventeen: Resolves Header Image Quality Issue

The heading image had quality issues on iOS Safari in portrait and landscape modes. This resolves it through adding 200cv for smaller screens so less than full size.

Props poena, richardevs, laurelfulford, davidakennedy, joemcgill, SergeyBiryukov, ianbelanger, sabernhardt, shailu25, robertghetau.
Fixes #39253.
