Move config files to CLI modules with lazy proxies

Move jest config files to cli-module-test-jest/config and node
transform + webpack-public-path to cli-module-build/config. Replace
originals in @backstage/cli/config with lazy proxies that forward
to the appropriate module or throw if it is not installed.
