Rob Bradford 7989e46f8b virtio-devices: iommu: Pass size to translate_gva/translate_gpa ...

The DmaRemapping translate_gva and translate_gpa entry points discarded
the size argument that AccessPlatform's signature already carries and
only checked the base address. A buffer beginning inside a mapping but
extending past it was treated as fully translated, allowing reads or
writes outside the IOMMU-authorized window.

Add `size` to the trait, validate the full span fits in a single
mapping, and propagate it through AccessPlatformMapping.
