Add concentr/perbillion structure

Description

This is to handle the ICU side for supporting the new unit portion-per-1e9 on the CLDR side. ('portion' to match permillion, etc)

On the CLDR side, this is a compound unit; the LDML syntax will be extended for it (PR coming up soon).

We have a request to add concentr/perbillion as a new supported unit in CLDR/ICU in order to support pollution measurements.

Is there a PR yet?

I created as a workaround for 76.1

Needs to be reverted once this is fixed.

ICU-TC discussion

  • percent & permille are separate units

  • this is proposing something new really, treating the number-only denominator as a unit

  • we should not hack another per-billion

  • ideally handled via a new thing, a dimensionless unit

  • then percent & permille need to be made to work seamlessly with that

  • this should not be rushed at this time in the release cycle

  • priority for ICU 77

came back to work and said he will take it so I stop working on this after I found the grammar issue and reported to Mark.
