Add an IMPL_DEFINED pixel format. 

This change adds a new HAL pixel format that indicates that the specific format
is to be chosen by the gralloc implementation.

     * format from those usage flags.  This format will never be used with any

     * of the GRALLOC_USAGE_SW_* usage flags.

     * If a buffer of this format is to be used as an OpenGL ES texture, the

     * framework will assume that sampling the texture will always return an

     * alpha value of 1.0 (i.e. the buffer contains only opaque pixel values).
