DDSIRTP23 — Reorganizing section 9.3.2

Section 9.3.2 largely consists of a single 5-page table (Table 9.4). This creates a usability issue for the spec where important lists of constants (like the BuiltinEndpointSet_t values) need to be found within the huge table instead of directly being referred to by other parts of this spec or other specs (Security).

Split Table 9.4

When current rows of Table 9.4 contain their own tables of constants (beyond just trivial constants that we don't expect to change in future minor versions), make these constants their own tables.
