Support airgapped bitstream/DV flow

Allow using an archive path for some cores to build bitstream targets in an
air-gapped environment. The files of the cores are expected to be built
offline

To enable the config for bitstream, run

bazel build --config=airgapped_env <bitstream target>

For DV, add airgapped cores-root path allowing fusesoc to find the
chisel-built cores.

Test: bazel cquery "deps(//hw/bitstream/vivado:fpga_nexus)"
[--//rules:build_env='airgapped'] and check
dependencies
