[CTS incremental] Genrule to include test app dependencies in build

cts test succeed with the atest command but not with cts-tradefed. This is because the idsigs and apks for splits weren't being copied to locations searchable by tradefed buildinfo. These genrules copies the missing files.

Test: cts-tradefed run cts -m CtsIncrementalInstallHostTestCases
