target/arm: Enable FEAT_Debugv8p2 for -cpu max

Browse source 
The only portion of FEAT_Debugv8p2 that is relevant to QEMU
is CONTEXTIDR_EL2, which is also conditionally implemented
with FEAT_VHE.  The rest of the debug extension concerns the
External debug interface, which is outside the scope of QEMU.
