Fix CBOR tag handling in cbor_tag_handler_t::store for non-binary items (#5559)

When using cbor_tag_handler_t::store, tags 0xD8-0xDB previously assumed
that the tagged item was a byte string, unconditionally attempting to
parse binary data and failing on valid CBOR documents containing tags
applied to integers, strings, arrays, or objects (such as self-describe
tag 55799).

Check whether the tagged data item is a byte string (0x40-0x5B or 0x5F).
If it is a byte string, store the subtype on the binary value as before.
Otherwise, iteratively process the tagged value in the driver loop using
item_read so that chained tags do not consume native stack space.

Part of #5316.
