Moved all files from include/system to libsystem/include/system

Bug: 33241851
Test: No changes for modules not using VNDK. For compiling with VNDK,
add libsystem_headers as dependency for using these headers

+/**
+ * A set of bit masks for specifying how the received preview frames are
+ * handled before the previewCallback() call.
+ *
+ * The least significant 3 bits of an "int" value are used for this purpose:
+ *
+ * ..... 0 0 0
+ *       ^ ^ ^
+ *       | | |---------> determine whether the callback is enabled or not
+ *       | |-----------> determine whether the callback is one-shot or not
+ *       |-------------> determine whether the frame is copied out or not
+ *
+ * WARNING: When a frame is sent directly without copying, it is the frame
+ * receiver's responsiblity to make sure that the frame data won't get
+ * corrupted by subsequent preview frames filled by the camera. This flag is
+ * recommended only when copying out data brings significant performance price
+ * and the handling/processing of the received frame data is always faster than
+ * the preview frame rate so that data corruption won't occur.
+ *
+ * For instance,
+ * 1. 0x00 disables the callback. In this case, copy out and one shot bits
+ *    are ignored.
+ * 2. 0x01 enables a callback without copying out the received frames. A
+ *    typical use case is the Camcorder application to avoid making costly
+ *    frame copies.
+ * 3. 0x05 is enabling a callback with frame copied out repeatedly. A typical
+ *    use case is the Camera application.
+ * 4. 0x07 is enabling a callback with frame copied out only once. A typical
+ *    use case is the Barcode scanner application.
