run a host tool produced by the build
usage: fx host-tool [--no-build] TOOLNAME [TOOL_ARGS...] This looks for a tool named TOOLNAME in tool-paths.json and executes it with the provided TOOL_ARGS. --no-build does not attempt to build the tool if it does not exist --check-firewall print a warning if the tool isn't included in firewall rules. This is a no-op outside of macOS. --print print the tool path instead of executing it. TOOL_ARGS is ignored, but check-firewall and build behaves the same. If the tool is not known to the build system, for example if it is not in the GN build graph, a proper message will be printed and the script fails. This script is specially useful for other scripts, via fx-command-run, although it can also be used directly by final users. The tool will be built if host-tool is being run interactively, otherwise an error will be produced if the tool is missing.
