x86/entry: Remove support for partial cpu_user_regs frames

Save all GPRs on entry to Xen.

The entry_int82() path is via a DPL1 gate, only usable by 32bit PV guests, so
can get away with only saving the 32bit registers. All other entrypoints can
be reached from 32 or 64bit contexts.

This is part of XSA-254.
