[Sanitizer] Add #include to fix (some) Windows build

[sberg]

Summary

After 56dec4be9bd321a8fc0f19df00a8d63fc44813f5 "[Sanitizer] Allow setting the report path to create directory" introducing a call to _mkdir, at least my Windows build using VS 2022 Preview (17.0.0 Preview 4.1) started to fail with

compiler-rt\lib\sanitizer_common\sanitizer_win.cpp(568): error C3861: '_mkdir': identifier not found

and https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/mkdir-wmkdir?view=msvc-160 "_mkdir, _wmkdir" says this requires <direct.h>.

For some reason patch application is failing on CI, while on local system it is fine. I reported this on here - https://github.com/google/llvm-premerge-checks/issues/351.
