Fix https://bugs.llvm.org/show_bug.cgi?id=43830 while avoiding polluting the global Python namespace. This both reverts r357277 to rebundle a version of Python's readline module based on libedit. However, this patch also provides two improvements over the previous implementation: 1. use PyMem_RawMalloc instead of PyMem_Malloc, as expected by PyOS_Readline (prevents to segfault upon exit of interactive session) 2. patch the readline module upon embedded interpreter loading, instead of patching it globally, which should prevent any side effect on other modules/packages 3. only activate the patched module if libedit is actually linked in lldb Differential Revision: https://reviews.llvm.org/D69793
