[build] remove unused Swarming xcode install scripts

run_swarming_xcode_install.py triggers a Swarming task to install Xcode using Isolate server.
But Isolate server will be deprecated, soon.

I don't see the Xcode install Swarming tasks in BigQuery. (past 1.5 years)

So should be safe to remove them.

-This script runs swarming_xcode_install on the bots.  It should be run when we
-need to upgrade all the swarming testers.  It:
-  1) Packages two python files into an isolate.
-  2) Runs the isolate on swarming machines that satisfy certain dimensions.
-
-Example usage:
-  $  ./build/run_swarming_xcode_install.py  --luci_path ~/work/luci-py \
-       --swarming-server touch-swarming.appspot.com \
-       --isolate-server touch-isolate.appspot.com
