Removing the option --tdx to specify that we want to run a TD VM. Rely
on --platform option by adding the "tdx" boolean parameter. This is the
new way for enabling TDX with Cloud Hypervisor.
Along with this change, the way to retrieve the firmware path has been
updated to rely on the recently introduced PayloadConfig structure.

Adding a new limitation related to the TDX guest kernel as it doesn't
allow for most ACPI devices, meaning the PCI hotplug through ACPI isn't
supported unless we use 'tdx_disable_filter' boot parameter.

According to latest official images based on latest TDX guest kernel, we
update the documentation to reflect the change regarding serial support.
New guest kernels have been updated to disable usage of serial ports,
meaning adding console=ttyS0 to the kernel boot parameters will have no
effect.
