Subject: [PATCH 1/2] [clangd] Update clangDaemonTweaks to set symbol
visibility macros correctly
This will fix linker duplicate symbols errors from clangDaemonTweaks exporting
clang symbols instead of importing them for windows shared library builds using
explicit symbol visibly.
This is part of the work to enable LLVM_BUILD_LLVM_DYLIB and LLVM/Clang
plugins on window.
