Subject: structured compute basics (#714)

this change adds the `zencompute` component, which can be used to distribute work dispatched from UE using the DDB (Derived Data Build) APIs via zenserver

this change also adds a distinct zenserver compute mode (`zenserver compute`) which is intended to be used for leaf compute nodes

to exercise the compute functionality without directly involving UE, a `zen exec` subcommand is also added, which can be used to feed replays through the system

all new functionality is considered *experimental* and disabled by default at this time, behind the `zencompute` option in xmake config
