Fix texture image internalformat/type validation.

Fix texture image internalformat/type validation.

checkInternalFormat() was not properly checking that the Skia bitmap
color type matches the OpenGL format and type combination. In some
cases this would lead to visual artifacts (e.g. when a 565 type is
uploaded to a 4444 type), while in other cases it would cause reading
out of bounds (e.g. when uploading Alpha_8 with a GL_RGBA format).

Note that valid Bitmap formats are documented at
https://developer.android.com/reference/android/graphics/Bitmap.Config.html
checkInternalFormat() now also matches getInternalFormat() and
getType().
