feat(rdn2): enable MTE2 if present on the platform

Browse source 
MTE2 is an optional feature that could be part of platforms based on Arm
V8.5 or above. If this feature is implemented on the platform, lower ELs
could potentially access the featre registers leading EL3 traps.
Therefore, set MTE2 build option to '2' to enable the feature only if
its implemented on the platform.
