[roll] Roll fuchsia [fxfs] implement write support for fallocate
Add several things to support writing to allocated regions -
- Add AllocatedRanges which can track pre-allocated ranges in memory.
- When opening an object, if the object is indicated to have overwrite
extents, find them and record them.
- Use the tracked allocated ranges in PagedObjectHandle to put overwrite
ranges into their own batches.
- Add multi_overwrite, which can write to existing overwrite extents.
