This patch adds the /linkreprofullpathrsp flag with the same behaviour as link.exe. This flag emits a file containing the full paths to each object passed to the link line. This is used in particular when linking Arm64X binaries, as you need the full path to all the Arm64 objects that were used in a standard Arm64 build. See: https://learn.microsoft.com/en-us/cpp/build/reference/link-repro-full-path-rsp for the Microsoft documentation of the flag. Relands #165449
