x86: mmio, inmates/tests: Add support for movb-from-mem
We already support movb-to-mem, adding the reverse direction is simple.
Accompany this with tests for both 8-bit accesses.

x86: Fix long mode detection
If the guest is currently running in long mode does not only depend on
EFER having it enabled. We also need to check if CS.L is set. If L is 0,
we are actually in compatibility mode.
Rework vcpu_vendor_get_cs() to vcpu_vendor_get_cs_attr() so that it
returns all needed information about the CS segment. This includes L,
the DPL for the current privilege level and already the D/B bit which
will be needed soon by the instruction parser.

Log Message:
-----------
x86: mmio: Fix address width calculation
As we are claiming to support the affected instructions, we should get
this completely right: When not in long mode, the combination of the
address-size prefix and the D/B bit from CS defines if we are using 16
or 32 bit addresses.
A similar pattern may eventually be useful to support the operand-size
prefix for with 16-bit accesses.

Log Message:
-----------
inmates: tests: Add x86-32 MMIO test case
Mostly the 32-bit equivalent of the existing 64-bit case, just removing
long-mode-only tests and converting to 32-bit data/address size where
needed.
