target/i386: Add support for save/load of exception error code
For now, qemu save/load CPU exception info(such as exception_nr and
has_error_code), while the exception error_code is ignored. This will
cause the dest hypervisor reinject a vCPU exception with error_code(0),
potentially causing a guest kernel panic.
For instance, if src VM stopped with an user-mode write #PF (error_code 6),
the dest hypervisor will reinject an #PF with error_code(0) when vCPU resume,
then guest kernel panic as:
BUG: unable to handle page fault for address: 00007f80319cb010
#PF: supervisor read access in user mode
#PF: error_code(0x0000) - not-present page
RIP: 0033:0x40115d
To fix it, support save/load exception error_code.

Log Message:

x86/loader: Don't update kernel header for CoCo VMs
Update the header makes it different from the original kernel that user
provides via "-kernel", which leads to a different hash and breaks the
attestation, e.g., for TDX.
We already skip it for SEV VMs. Instead of adding another check of
is_tdx_vm() to cover the TDX case, check machine->cgs to cover all the
confidential computing case for x86.

-----------
i386/tcg/svm: fix incorrect canonicalization
For all 32-bit systems and 64-bit Windows systems, "long" is 4 bytes long.
Due to using "long" for a linear address, svm_canonicalization would
set all high bits to 1 when (assuming 48-bit linear address) the segment
base is bigger than 0x7FFF.
This fixes booting guests under TCG when the guest IDT and GDT bases are
above 0x7FFF, thereby resulting in incorrect bases. When an interrupt
arrives, it would trigger a #PF exception; the #PF would trigger again,
resulting in a #DF exception; the #PF would trigger for the third time,
resulting in triple-fault, and eventually causes a shutdown VM-Exit to
the hypervisor right after guest boot.

rust: declare self as qemu_api for proc-macros
Fix an outstanding TODO.
Declaring `extern crate self as qemu_api` allows use of `qemu_api`
within the qemu_api crate; this allows the Wrapper derive macro and
future proc macros to be used interchangeably in the qemu_api crate and
other crates. This is not required currently and is only for
future-proofing.
