target/i386: Pass host pointer and size to cpu_x86_{xsave,xrstor}
We have already validated the memory region in the course of
validating the signal frame. No need to do it again within
the helper function.
In addition, return failure when the header contains invalid
xstate_bv. The kernel handles this via exception handling
within XSTATE_OP within xrstor_from_user_sigframe.

linux-user/i386: Fix allocation and alignment of fp state
For modern cpus, the kernel uses xsave to store all extra
cpu state across the signal handler. For xsave/xrstor to
work, the pointer must be 64 byte aligned. Moreover, the
regular part of the signal frame must be 16 byte aligned.
Attempt to mirror the kernel code as much as possible.
Use enum FPStateKind instead of use_xsave() and use_fxsr().
