[CMake] Fix pthread handling for out-of-tree builds
...
LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects
to correctly link the threading library when needed. Unfortunately
`PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed
and therefore can't be used when configuring out-of-tree builds. This causes
such builds to fail since `pthread` isn't being correctly linked.
This patch attempts to fix that problem by renaming and exporting
`LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB`
because It seemed likely to cause collisions with downstream users of
`LLVMConfig.cmake`.

[libFuzzer] Export external functions on tests.
...
We need to export external functions so they are found when calling
GetProcAddress() on Windows. But we can't use `__declspec(dllexport)` because
we want the targets to be completely independent from the fuzz engines and don't
depend on other header files. Also, we don't want to include platform specific
code managed with conditional macros.
So, the solution is to add the exported symbols with linker flags in cmake.
