Remove SkKTXImageEncoder

It escaped the chopping block when we deleted the decoder, but it is
currently untested and unused as far as we know. In addition to
removing effectively unsupported code, this simplifies build file
changes (i.e. don't build it on Android framework, but build it
elsewhere) as we narrow our build systems down to one.

-// KTX Image Encoder
-//
-// KTX is a general texture data storage file format ratified by the Khronos Group. As an
-// overview, a KTX file contains all of the appropriate values needed to fully specify a
-// texture in an OpenGL application, including the use of compressed data.
-//
-// This encoder takes a best guess at how to encode the bitmap passed to it.
-// The KTX library tries to do its best to encode the appropriate
-// data specified by the bitmap based on the config. (i.e. kAlpha8_Config will
-// be represented as a full resolution 8-bit image dump with the appropriate
-// OpenGL defines in the header).
