Lots of constants values from propkey.h are missing

Unless I'm mistaken, some constants values defined in propkey.h are missing in metadata, for example:

```
#define CALENDAR_RESPONSESTATUS_NONE 0u
#define CALENDAR_RESPONSESTATUS_ORGANIZED 1u
#define CALENDAR_RESPONSESTATUS_TENTATIVE 2u
#define CALENDAR_RESPONSESTATUS_ACCEPTED 3u
#define CALENDAR_RESPONSESTATUS_DECLINED 4u
#define CALENDAR_RESPONSESTATUS_NOTRESPONDED 5u

#define CALENDAR_SHOWTIMEAS_FREE 0u
#define CALENDAR_SHOWTIMEAS_TENTATIVE 1u
#define CALENDAR_SHOWTIMEAS_BUSY 2u
#define CALENDAR_SHOWTIMEAS_OOF 3u

#define COMMUNICATION_DIRECTION_UNKNOWN 0u
#define COMMUNICATION_DIRECTION_INCOMING 1u
#define COMMUNICATION_DIRECTION_OUTGOING 2u

...

#define PHOTO_ORIENTATION_NORMAL 1u
#define PHOTO_ORIENTATION_FLIPHORIZONTAL 2u
#define PHOTO_ORIENTATION_ROTATE180 3u
#define PHOTO_ORIENTATION_FLIPVERTICAL 4u
#define PHOTO_ORIENTATION_TRANSPOSE 5u
#define PHOTO_ORIENTATION_ROTATE270 6u
#define PHOTO_ORIENTATION_TRANSVERSE 7u
#define PHOTO_ORIENTATION_ROTATE90 8u
...

```
However, some are defined, like these:

```
#define SYNC_STATE_NOTSETUP 0ul
#define SYNC_STATE_SYNCNOTRUN 1ul
#define SYNC_STATE_IDLE 2ul
#define SYNC_STATE_ERROR 3ul
#define SYNC_STATE_PENDING 4ul
#define SYNC_STATE_SYNCING 5ul

```

Start by examining propkey.h and comparing its defined constants with the constants present in the generated metadata. Use the listed CALENDAR_RESPONSESTATUS, PHOTO_ORIENTATION, and SYNC_STATE values as comparison cases. Done means the missing propkey.h constants are represented consistently in metadata, with any applicable metadata validation passing.
