Revert "Adding support for RGBA_4444 tile textures"

This reverts commit 8e6d15826280b9f11a28060b5b2d2bbef17d15bc (r223830; http://crrev.com/21159007).

Although the 4444 textures work on S4, they break on N7v2 and N10.
(We've got inconsistent reports about N4.)
Passing --disable-4444-textures isn't sufficient to fix the problems.

ilevy@ points out that the commit bot is using GN, so could easily have missed this breakage. We're hoping to switch to N4, but in this case there's no guarantee that that would have caught it either.

Perhaps the main patch can be landed in pieces next time?
