fix(rdv3): handle invalid build combination

Browse source 
`CTX_INCLUDE_SVE_REGS` should not be enabled when building with
SPD=spmd and SPMD_SPM_AT_SEL2=1 both been used.

Unfortunately a check at top level makefile ignored this, now its been
fixed at top level makefile. Ensure correct combination are handled,
otherwise it will lead to build failures.
