target/arm: Enable FEAT_CSV2_3 for -cpu max

FEAT_CSV2_3 adds a mechanism to identify if hardware cannot disclose
information about whether branch targets and branch history trained
in one hardware described context can control speculative execution
in a different hardware context.

There is no branch prediction in TCG, so we don't need to do anything
to be compliant with this.  Upadte the '-cpu max' ID registers to
advertise the feature.
