feat(fvp): enable FEAT_FGT by default
FEAT_FGT is one of the features for which Linux necessarily requires EL3
enablement, when the feature is present on a PE.
To cover the effect of different FVP command line parameters, include
the feature into the standard FVP build, but use FEAT_STATE_CHECK, to
always do runtime checks before accessing feature specific registers.
This prevents a Linux crash when the FVP is called with FEAT_FGT
enabled.
