.. from the guts of GDBRemoteCommunication to ~top level. This is motivated by #131519 and by the fact that's impossible to guess whether the author of a symlink intended it to be a "convenience shortcut" -- meaning it should be resolved before looking for related files; or an "implementation detail" -- meaning the related files should be located near the symlink itself. This debate is particularly ridiculous when it comes to lldb-server running in platform mode, because it also functions as a debug server, so what we really just need to do is to pass /proc/self/exe in a platform-independent manner. Moving the location logic higher up achieves that as lldb-platform (on non-macos) can pass `HostInfo::GetProgramFileSpec`, while liblldb can use the existing complex logic (which only worked on liblldb anyway as lldb-platform doesn't have a lldb_private::Platform instance). Another benefit of this patch is a reduction in dependency from GDBRemoteCommunication to the rest of liblldb (achieved by avoiding the Platform dependency).
