Add the ExtTrcBuff field definitions to ID_AA64DFR0_EL1 from
DDI0601 2023-09.

This field isn't used yet. Adding it for completeness and because
it will be used in future patches.

There's also updates for PMSVer, PMUVer and DebugVer, and the addition
of SEBEP and PSSS.  The changes here are fine though
