target/arm: Report HCR_EL2.{NV,NV1,NV2} in cpu dumps

When interpreting CPU dumps where FEAT_NV and FEAT_NV2 are in use,
it's helpful to include the values of HCR_EL2.{NV,NV1,NV2} in the CPU
dump format, as a way of distinguishing when we are in EL1 as part of
executing guest-EL2 and when we are just in normal EL1.

Add the bits to the end of the log line that shows PSTATE and similar
information:

PSTATE=000003c9 ---- EL2h  BTYPE=0 NV NV2
