x86: mmio: fix accidental clears of bits in registers
We trap certain MMIO accesses and need to emulate their access.
On x86, a 32-bit read will clear bits 32-63 of a register.
Inconsistently, on x86, 16-bit and 8-bit reads must not clear high bits.
Jailhouse erroneously cleared those bits. Prevent this by applying a
preserved mask that keeps bits alive.
Add tests that check correct behaviour.

x86: mmio: move flags to struct parse_context
We can easier pass them around if flags are stored in struct
parse_context.
Just a preparation, no functional change so far.

Log Message:
-----------
x86: mmio: add support for 0x66 operand prefix
mov (%rax), %ax is a 16-bit data MOV_FROM_MEM that will emit
0x66 0x8b 0x00.
0x66 is the operand-size override prefix which we currently do not support.
We should support it, as we can find this opcode, for example, for some
mmconfig space access from Linux (e.g., pci_generic_config_read).
This also adds appropriate mmio-access tests.
Tested in QEMU virtual target.
