(conan-io#9299) Add a with_extras option to the ICU package

* Add a with_extras option to the ICU package

ICU is configured with --disable-extras by default, and this commit makes
it possible to turn it on with the option "icu:with_extras=True".

* Gate environment settings on the options that need them.
