Auto merge of #122596 - rcxdude:master, r=petrochenkov

Use MSVC-style escaping when passing a response/@ file to lld on windows

LLD parses @ files like the command arguments on the platform it's on, so on windows it needs to follow the MSVC style to work correctly. Otherwise builds can fail if the linker command gets too long and the build path contains spaces.
