Fix cmake config file

Removed cmake target files under packaging directory.

Merged cmake config .in files for HIP-Clang and HCC as one.

Use cmake generated target files in both install and packaging.

This makes cmake config file consistent for make install and
make package.

Let device side malloc/free return nullptr and trap
