zig build: remove --build-runner CLI parameter

There is no concept of a "build runner" any more; it has been split in two:
configurer and maker.

Users of this feature will likely want to no longer override any logic, and
instead consume the configuration file produced by configurer.

If overriding one or the other of these is desired, the feature will need to be
re-introduced (as --override-maker or --override-configurer).
