Consider capturing git the line break configuration in sourcelink json

This change in .NET SDK added assembly-level attribute with git repo clone URL: https://github.com/dotnet/sdk/pull/11559

This can be used to optimize download of all source file required to build the dll. If however, the git configuration (specifically `core.eol` and `core.autocrlf` settings) differ between the server that originally built the DLL and the local repo the re-build will produce different binaries.

It would thus be useful to record the git settings in Source Link record so that the clone can be configured the same as the build server that produced the binary.

Note: Check if git line conversion changes the BOM.
