In charts, make "min" and "max" into pure functions and formally mark pure functions as pure

Browse source 
Summary:
Depends on D20814. Currently, "min()" and "max()" are still "min(f, n)". This is no longer consistent with the construction of functions a function-generators that are composed at top level.

Turn them into "min(n)" and "max(n)" (i.e., not higher-order functions).

Then, mark all the functions which are pure mathematical functions and not higher-order as "pure". These functions have no function parameters and do not reference external data. For now, this distinction has no immediate implications, but it will simplify the next change (which tracks where data came from when it originated from an external source -- these pure functions never have any source information, since they only apply pure mathematical transformations to data).

Test Plan: Loaded a burnup chart, nothing seemed obviously broken.
