Add sdk_version:"none" to replace no_standard_libs:true

Where possible this duplicates any tests that use no_standard_libs:true
with ones that use sdk_version:"none". If not possible (e.g. in the
default targets included in java/testing.go) it switches some to use
sdk_version:"none" to ensure that there is no regression in the
behavior of no_standard_libs:true.

Follow up changes will switch all usages of no_standard_libs:true over
to use sdk_version:"none" at which point no_standard_libs will be
removed.
