Since the host IOVA ranges are now passed through the
PCIIOMMUOps set_host_resv_regions and we have removed
the only implementation of iommu_set_iova_range() in
the virtio-iommu and the only call site in vfio/common,
let's retire the IOMMU MR API and its memory wrapper.

Ask the ConfidentialGuestSupport object whether to use guest_memfd
for KVM-backend private memory. This bool can be set in instance_init
(or user_complete) so that it is available when the machine is created.

Replace translator_fake_ldb, which required multiple calls,
with translator_fake_ld, which can take all data at once.

We have eliminated most uses of this hook. Reduce
further by allowing the hook to handle only the
special cases, returning false for normal processing.

Do not pass around a boolean between multiple structures,
just read it from the TranslationBlock in the TCGContext.

This will be able to replace plugin_insn_append, and will
be usable for disassembly.

While there are other methods that could be used to replace
TARGET_PAGE_MASK, the function is not really required outside
the context of target-specific translation.
This makes the header usable by target independent code.

Instead of using a single global bounce buffer, give each AddressSpace
its own bounce buffer. The MapClient callback mechanism moves to
AddressSpace accordingly.
This is in preparation for generalizing bounce buffer handling further
to allow multiple bounce buffers, with a total allocation limit
configured per AddressSpace.
