Don't return the passthrough interface for getStub

getStub parameter to getService is only used for the
registerPassthroughServiceImplementation function so that
a passthrough service can be used as an implementation of
a binderized service.

Right now, this means the following calls are executed:
BpFoo -binder-> BnFoo -> BsFoo -> IFoo (impl)

But, after this change, it becomes:
BpFoo -binder-> BnFoo -> IFoo (impl)

Test: hidl_test
Test: (sanity) device boots
Test: redundant passthrough calls gone in systrace
Test: GL TextureView benchmark reduced jank

hidl-gen user guide

1. Build

croot
make hidl-gen

2. Run

hidl-gen -o output-path -L language (-r interface-root) fqname

output-path: directory to store the output files.
language: output file for given language. e.g.c++, vts..

fqname: fully qualified name of the input files.
For singe file input, follow the format: package@version::fileName
For directory input, follow the format: package@version

interface-root(optional): prefix and root path for fqname.
If not set, use the default prefix: android.hardware and default root path
defined in $TOP.

examples:

croot
hidl-gen -o output -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0::INfc.hal
hidl-gen -o output -L vts -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -o test -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -L hash -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
