KVM: arm64: Update and fix FGT register masks

Browse source

New trap bits have been defined since the latest update to this
patch.  Moreover, the existing definitions of some of the mask
and the RES0 bits overlap, which could be wrong, confusing, or
both.

Update the bits based on DDI0601 2023-09, and ensure that the
existing bits are consistent.

Subsequent patches will use the generated RES0 fields instead of
specifying them manually. This patch keeps the manual encoding of
the bits to make it easier to review the series.
