[lldb][AIX] 1. Avoid namespace collision on other platforms (llvm#104679)
This PR is in reference to porting LLDB on AIX. Link to discussions on llvm discourse and github: 1. https://discourse.llvm.org/t/port-lldb-to-ibm-aix/80640 2. llvm#101657 The complete changes for porting are present in this draft PR: llvm#102601 The changes on this PR are intended to avoid namespace collision for certain typedefs between lldb and other platforms: 1. tid_t --> lldb::tid_t 2. offset_t --> lldb::offset_t
