Add support for free page reporting. The idea is to function very similar
to how the balloon works in that we basically end up madvising the page as
not being used. However we don't really need to bother with any deflate
type logic since the page will be faulted back into the guest when it is
read or written to.

This provides a new way of letting the guest proactively report free
pages to the hypervisor, so the hypervisor can reuse them. In contrast to
inflate/deflate that is triggered via the hypervisor explicitly.

We need to make certain to advertise support for page poison reporting if
we want to actually get data on if the guest will be poisoning pages.

Add a value for reporting the poison value being used if page poisoning is
enabled in the guest. With this we can determine if we will need to skip
free page reporting when it is enabled in the future.

The value currently has no impact on existing balloon interfaces. In the
case of existing balloon interfaces the onus is on the guest driver to
reapply whatever poison is in place.

When we add free page reporting the poison value is used to determine if
we can perform in-place page reporting. The expectation is that a reported
page will already contain the value specified by the poison, and the
reporting of the page should not change that value.

bios-tables-test executes SeaBIOS. Indeed FW is needed to
fetch tables from QEMU and put them into the guest RAM. Also
the FW patches cross table pointers. At some point, SeaBIOS
ends up calling the TPM2_CC_HierarchyControl command with
TPM2_ST_SESSIONS tag, most probably steming from
tpm_set_failure/tpm20_hierarchycontrol SeaBIOS call path.
This causes an assert() in the qtest tpm emulation code.

As the goal here is not to boot SeaBIOS completely but just
let it grab the ACPI tables and consolidate them, let's just
remove the assert().

In Makefile.objs, the ui/ directory is restricted to system-mode:

 43 ifeq ($(CONFIG_SOFTMMU),y)
 ...
 65 common-obj-y += ui/
 66 common-obj-m += ui/
 ...
 82 endif # CONFIG_SOFTMMU

Restrict the ui/ stub added in commit 2df9f571 to only build
it for system-mode emulation.
