Hold MetadataV3 chunks in a Ref so resize! can replace the grid

A rectilinear grid depends on the array shape, which is already a Ref so
that `resize!` can change it. Rebuilding the regular axes on every read
left `metadata.chunks` stale and could not express a resized irregular
axis.

- `MetadataV3.chunks` is a `RefValue` holding an `NTuple` or `GridChunks`;
  `MetadataV2` is unchanged and shared code reads through `chunkspec`.
- Growing an irregular axis appends one chunk covering the added extent,
  as zarr-python does. Shrinking one still throws before mutating, since
  zarr-python expresses that with overflowing edges.
