Simplify full compilation from IR to binary executable

[nilslice]

Considering the current multi-step process to transform and compile bitcode to a native binary, we could simplify things for end-users a bit:

Adding a CLI operation a la:
qcs-sdk-qir compile input.bc -o program, which would transform the IR, compile the shared libraries, and compile the IR.

where program is the final executable, even statically linked with:

• LLVM libraries
• QCS helper C library
• QCS C SDK

Potential issues:

• cross-compilation / target configurability
• LLVM library linking
• clang/gcc/etc compiler configurability or automatic lookup of available options
• where to source the shared libraries
