  tcg: Add CPUClass::tlb_fill

This hook will replace the (user-only mode specific) handle_mmu_fault
hook, and the (system mode specific) tlb_fill function.

The handle_mmu_fault hook was written as if there was a valid
way to recover from an mmu fault, and had 3 possible return states.
In reality, the only valid action is to raise an exception,
return to the main loop, and deliver the SIGSEGV to the guest.

Note that all of the current implementations of handle_mmu_fault
for guests which support linux-user do in fact only ever return 1,
which is the signal to return to the main loop.

Using the hook for system mode requires that all targets be converted,
so for now the hook is (optionally) used only from user-only mode.

  target/mips: Pass a valid error to raise_mmu_exception for user-only

At present we give ret = 0, or TLBRET_MATCH.  This gets matched
by the default case, which falls through to TLBRET_BADADDR.
However, it makes more sense to use a proper value.  All of the
tlb-related exceptions are handled identically in cpu_loop.c,
so TLBRET_BADADDR is as good as any other.  Retain it.

Since the only non-negative TLBRET_* value is TLBRET_MATCH,
the subsequent test for ret < 0 is useless.  Use early return
to allow subsequent blocks to be unindented.

  tcg: Use CPUClass::tlb_fill in cputlb.c

We can now use the CPUClass hook instead of a named function.

Create a static tlb_fill function to avoid other changes within
cputlb.c.  This also isolates the asserts within.  Remove the
named tlb_fill function from all of the targets.

  tcg: Use tlb_fill probe from tlb_vaddr_to_host

Most of the existing users would continue around a loop which
would fault the tlb entry in via a normal load/store.

But for AArch64 SVE we have an existing emulation bug wherein we
would mark the first element of a no-fault vector load as faulted
(within the FFR, not via exception) just because we did not have
its address in the TLB.  Now we can properly only mark it as faulted
if there really is no valid, readable translation, while still not
raising an exception.  (Note that beyond the first element of the
vector, the hardware may report a fault for any reason whatsoever;
with at least one element loaded, forward progress is guaranteed.)
