arm64: Expand ESR_ELx_WFx_ISS_TI to match its ARMv8.7 definition

Browse source

Starting with FEAT_WFXT in ARMv8.7, the TI field in the ISS
that is reported on a WFx trap is expanded by one bit to
allow the description of WFET and WFIT.

Special care is taken to exclude the WFxT bit from the mask
used to match WFI so that it also matches WFIT when trapped from
EL0.
