Summary: This patch adds a modulemap which allows compiling the lldb headers into C++ modules (for example in builds with LLVM_ENABLE_MODULES=On). Even though most of the affected code has been cleaned up to work with the more strict C++ module semantics, there are still some workarounds left in the current modulemap (the most obvious one is the big `lldb` wrapper module). It also moves the Obj-C++ files in lldb to their own subdirectories. This was necessary because we need to filter out the modules flags for this code. Note: With the latest clang and libstdc++ it seems necessary to have a STL C++ module to get a working LLVM_ENABLE_MODULES build for lldb. Otherwise clang will falsely detect ODR violations in the textually included STL code inside the lldb modules.
