Fix MEDIA_LNK_FL_* and MEDIA_PAD_FL_* visibility in CLI translation unit

Browse Source 
The CLI is a separate translation unit that doesn't include <linux/media.h>,
so the kernel flag constants were undefined there. Fix by defining our own
public constants in media_ctrl.h:
- MEDIA_LINK_FL_{ENABLED,IMMUTABLE,DYNAMIC} for link flags
- MEDIA_PAD_FLAG_{SINK,SOURCE} for pad flags (distinct names avoid
  redefinition conflict with kernel's MEDIA_PAD_FL_* in media_ctrl.c)

media_ctrl.c now translates kernel flags to our constants on the way out.
Added fallback #defines for kernel constants that were missing them.
