Stop generating IHw classes.

The main rationale of the IHw class was to be able
to cast binder objects to/from interfaces safely.
That functionality is now taking over by interfaceChain()
in IBase, together with the toBinder()/fromBinder() functions
in libhidl.

The remaining binder objects related to IFoo are now just
BpFoo and BnFoo, and both still inherit from IInterface.

Note that the IHw *header* itself remains, as it contains the
declarations for reading/writing datatypes related to the
interface into a Parcel.

Test: mma, hidl_test, hidl_test_java

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
