Camera2: Add CAMERA2_HAL_PIXEL_FORMAT_ZSL temporarily.
Until all HAL implementations move to the new gralloc format selection
scheme, define FORMAT_ZSL for indicating ZSL streams.

+ * Temporary definition during transition.
+ *
+ * These formats will be removed and replaced with
+ * HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED. To maximize forward compatibility,
+ * HAL implementations are strongly recommended to treat FORMAT_OPAQUE and
+ * FORMAT_ZSL as equivalent to HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, and
+ * return HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED in the format_actual output
+ * parameter of allocate_stream, allowing the gralloc module to select the
+ * specific format based on the usage flags from the camera and the stream
+ * consumer.
