This is all the per-VMO info and mechanism except for

LogicalBufferCollection::allocation_result_info_, which we keep in sync with the set of

LogicalBuffer(s) in LogicalBufferCollection::buffers_.

This is always held in a std::unique_ptr

<

> instead of move-only because TrackedParentVmo

do_delete callbacks within need to capture a non-moving LogicalBuffer. We use std::unique_ptr

<

>

rather than shared_ptr

<

> or fbl::RefPtr

<

> because we need to ensure we can just delete all the

buffers in buffers_ if LogicalBufferCollection::Allocate() fails to allocate a later buffer.
