fix(fvp): enable FEAT_MTE2

Browse source 
ENABLE_FEAT_MTE2 controls the trapping of some MTE related system
registers. If the memory_tagging_support_level parameter on the FVP
command line is set to higher values, non-secure world will see the
feature bits in the CPU ID registers and will use those registers,
triggering a panic in BL31.

Enable the feature in the optional form for the FVP build, to avoid any
panics.
