collation element iterator needs to return quaternary-level data

Description

The collation element iterator currently returns primary+secondary+case+tertiary
level data. It also needs to return quaternary-level data (for shifted and
Hiragana). Add a function that returns all the bits. Reserve some bits for
further, future levels.

No need to return the identical level because that is just the NFD form of the
original string.
