Issue Details

---

This PR fixes repro package creation for ILCompiler by:

1. Covering the appropriate types received from the command line options parser (e.g., references from the response file are read as Dictionary<string,string>
2. Adding prefix to created directories in the repro package based on their usage (e.g., _in_ for inputs, _out_ for outputs)
3. Enabling creation of appropriate output directories in the repro package (e.g., --out:obj/Debug/native/hello.o becomes --out:_out_0/hello.o; where _out_0 is created in the archive as explained in (2))

Fixes #78921
