feat(trf): initialize trap settings of trace filter control registers access

Trap bits of trace filter control registers access are in
architecturally UNKNOWN state at boot hence

1. Initialized trap bits to one to prohibit trace filter control
   registers accesses in lower ELs (EL2, EL1) in all security states
   when FEAT_TRF is implemented.
2. These bits are RES0 when FEAT_TRF is not implemented and hence set
   it to zero to aligns with the Arm ARM reference recommendation,
   that mentions software must writes RES0 bits with all 0s.
