  [docs] [NFC] Clarify the datalayout documentation

This patch fixes a couple of small oversights in the documentation for
the datalayout specification:

* The v and f specifications are subject to the same constraints on <size>
as i is.
* The p[n] specification didn't mark <idx> as optional, despite
being documented and parsed as such.
* Similarly, none of the alignment specifications require <pref>.
