DDSIRTP25 — Revise list of Submessages EntityIDs and PIDs reserved for other specifications

It seems that some ranges reserved by other specifications (e.g. XTypes type service) are missing from RTPS. They should be added:

9.4.5.1.1.1 for SubmessageIDs
to 9.3.1.3.1 for the EntityIDs
Table 9.12 for ParameterIDs

Maybe always list the same set of specs: DDS Security, XTypes, DDS-RPC? and indicate explicitly if a specification does not reserve anything.

Also figure out whether new builtin endooints show up under the "availableBuiltinEndpoints" see Table 8.73 also the IDL in 9.3.2
Right now there is a comment in the IDL that says:

/* Bits 12-15 have been reserved by the DDS-Xtypes 1.2 Specification
and future revisions thereof.
Bits 16-27 have been reserved by the DDS-Security 1.1 Specification
and future revisions thereof.
*/

Maybe this needs ti be more explicit and get its own section.

Be more explicit about submessageID, PatameterIDs and EndpointIDs reserved by other DDS specifications

Create a new subsection to describe the reserved bits in the availableBuiltinEndpoints.

Add information to section 9.3.1.3.1 'EntityIds Reserved by other Specifications' to include the endpoints reserved by XTYPES

Add a new subsection under 9.3.2 'Mapping of the Types that Appear Within Submessages or Built-in Topic Data' to fully describe the content of the 9.3.2.12 BuiltinEndpointSet_t

Create new subsection before 9.6.5 'ParameterIds Deprecated by the Protocol' to define parameter IDs reserved by other specifications.
