[clang][MinGW] Add asan DLL lib before other libs and objects
As stated in https://github.com/llvm/llvm-project/issues/61685, by
passing LLD the import lib of the asan DLL first, the asan DLL will be
listed as the first entry in the Import Directory Table, making it be
loaded first before other user DLLs. This allows asan to be initialized
as early as possible to increase its instrumentation coverage to include
other DLLs not built with asan.
This also avoids some false asan reports on `realloc` for memory
allocated during initialization of user DLLs being loaded earlier than
asan, because after this change they will be loaded later than asan.
