  [Driver][MSVC] Pass profile file to lld-link via -lto-sample-profile option (#127442)

In SPGO lto mode, linker needs -lto-sample-profile option to set sample
profile file.
Linux adds this option by transferring fprofile-sample-use to
-plugin-opt=sample-profile=, which is alias of lto-sample-profile. (in
clang\lib\Driver\ToolChains\CommonArgs.cpp: tools::addLTOOptions()).
But clang on Windows misses the transferring. So add it now.
