[css3-text] dropping min/opt/max values for word-spacing

At the F2F the other week there was a resolution to drop the
minimum/optimum/maximum for word-spacing:

> fantasai: Actually, 2 things I want to drop from the spec currently:
> fantasai: (1) 'text-align: start end'
> fantasai: (2) word-spacing can take up to 3 values defining minimum
>           optimum maximum; don't have any implementations and would prefer to
>           drop and figure out justification limits in level 4
> Bert: do we want to have limits or do we want to allow other algorithms as well?
> Bert: I'm ok with dropping it, not sure we should add it back in afterwards.
> fantasai: I think we should drop it until we have a clear idea what we want for that.
> Koji: seems like consensus to drop
> RESOLVED: drop minimum/optimum/maximum values for word-spacing

I think these edits need be done before LC.
