[API] Make hb_face_reference_table() return empty blob instead of NULL
The idea here is that:
- Like pretty much all other API in harfbuzz, user does not have to
check for NULL.
- In any caller code, the case of missing table should be handled
exactly the same way that a too-short table is handled. Turning
a non-existent talbe into a table of size 0 makes the user code
safer.
