[build][scripts] Integrate Zircon via new GN build rather than old make build

build-zircon.sh and thus `fx build-zircon` now runs gn (if necessary) and
ninja (just once) rather than running `make` several times.  The extra
arguments previously taken as make arguments are now taken as either GN
build arguments or ninja arguments.

`fx set` now runs Zircon's `gn gen` before Fuchsia's `gn gen`, which
consumes files generated by the former.

Zircon-related GN build arguments are gone.  Zircon configuration
can be controlled via arguments to build-zircon.sh instead.

Note this also means that `zircon_boot_groups="all"` behavior is now
always on.  That is, the BOOTFS in the Fuchsia boot images will be
fatter and contain all of the Zircon tools and tests in `/boot`.
Zircon tests now appear in `/boot/test` rather than `/system/test`.

Bug: BLD-325 #comment Fuchsia GN integration adapted to Zircon GN legacy support
Test: manual
