Add sdk_version:"core_platform" to replace no_framework_libs:true

Where possible this duplicates any tests that use no_framework_libs:true
with ones that use sdk_version:"core_platform". If not possible (e.g. in the
default targets included in java/testing.go) it switches some to use
sdk_version:"core_platform" to ensure that there is no regression in the
behavior of no_framework_libs:true.

Follow up changes will switch all usages of no_framework_libs:true over
to use sdk_version:"core_platform" at which point no_framework_libs will be
removed.
