Don't force lcd on non-opaque portion of layer.

SkCanvas::saveLayerPreserveLCDTextRequests allows for lcd in layers but
forces the user to ensure that the lcd text is only drawn on opaque parts
of the layer. Otherwise the behavior is more or less undefined. This GM
did this on purpose to demonstrate, but it turns out this is unstable and
depends on the alignment of the glyph masks in CPU. Since we don't support
this mode anyway, drop it from the gm.
