Add native runtime components to Crossgen2 package. (#38600)

For Windows, add clrcompression.dll to the package. For Linux, add { libSystem.IO.Compression.Native.so, libSystem.Native.so, libSystem.Net.Security.Native.so, libSystem.Security.Cryptography.Native.OpenSsl.so } to the package and also remove the corresponding static libraries with the .a extension from crossgen2.deps.json.
