perf thread: Add accessor functions for thread

Using accessors will make it easier to add reference count checking in
later patches.

Committer notes:

thread->nsinfo wasn't wrapped as it is used together with
nsinfo__zput(), where does a trick to set the field with a refcount
being dropped to NULL, and that doesn't work well with using
thread__nsinfo(thread), that loses the &thread->nsinfo pointer.

When refcount checking is added to 'struct thread', later in this
series, nsinfo__zput(RC_CHK_ACCESS(thread)->nsinfo) will be used to
check the thread pointer.
