LOG: [libclang] Add missing dllexport annotation (#147108)

All other declarations of clang-c already have CINDEX_LINKAGE.

This missing annotation causes a linker error when building
`tools/clang/unittests/libclang/CrashTests/libclangCrashTests.exe` for
the Cygwin target.
On the regular Win32 target, this issue went unnoticed because the
entire libclang gtest-based testsuite is currently disabled for that
platform.

Added: 
    

Modified: 
    clang/include/clang-c/FatalErrorHandler.h

Removed:
