Build both AIDL and HIDL targets.

Merged from http://go/wvgerrit/147689

The default is to build for AIDL Widevine service.
Use "-t hidl" in build_and_run_all_unit_tests.sh or
build_all_unit_tests.sh to build for HIDL service.

Test: ./build_all_unit_tests -t hidl
Test: ./build_and_run_all_unit_tests -t hidl
Test: ./build_all_unit_tests
Test: ./build_and_run_all_unit_tests
