Make VtsHalWeaverTargetTest test both HIDL and AIDL services

VtsHalWeaverTargetTest and VtsHalWeaverV1_0TargetTest are identical
except for whether they use AIDL or HIDL.  Unfortunately, the HIDL test
is needed for several more years.  For now, we have to make some
substantial fixes to both tests.  To make continued maintenance of this
test easier, update VtsHalWeaverTargetTest to handle both AIDL and HIDL.
The test cases are still written in terms of the AIDL API, so it should
still be straightforward to remove HIDL support when the time comes.
