perf callchain: Refactor inline_list to operate on symbols
This is a requirement to create real callchain entries for inlined frames. Since the list of inlines usually contains the target symbol too, i.e. the location where the frames get inlined to, we alias that symbol and reuse it as-is is. This ensures that other dependent functionality keeps working, most notably annotation of the target frames. For all other entries in the inline_list, a fake symbol is created. These are marked by new 'inlined' member which is set to true. Only those symbols are managed by the inline_list and get freed when the inline_list is deleted from within inline_node__delete.
