[llvm] [Bazel] Fix Host target's exported headers to include windows (PR #213018)

[David Young via llvm-commits]

https://github.com/youngd007 created https://github.com/llvm/llvm-project/pull/213018

When PR# 201283 added windows os select to the build of the Host target, it missed the exported headers since the CI checks run only linux and mac (and I hadn't gotten to this in my slow slog of windows bazel lldb support).  I found when translating to BUCK and running into this compilation error on windows for buck2 built lldb.  
Still cannot build and claude tells me the exclude is necessary to avoid a duplicate.

claude assisted with bazel rule creation
