perf bpf-filter: Support multiple events properly

perf bpf-filter: Support multiple events properly

So far it used tgid as a key to get the filter expressions in the
pinned filters map for regular users but it won't work well if the has
more than one filters at the same time.  Let's add the event id to the
key of the filter hash map so that it can identify the right filter
expression in the BPF program.

As the event can be inherited to child tasks, it should use the primary
id which belongs to the parent (original) event.  Since evsel opens the
event for multiple CPUs and tasks, it needs to maintain a separate hash
map for the event id.

In the user space, it keeps a list for the multiple evsel and release
the entries in the both hash map when it closes the event.
