[PATCH v1 1/2] gdb: rename any_thread_of_inferior to any_non_exited_thread_of_inferior

The name any_thread_of_inferior suggests that the function may return
any thread of the inferior. In practice, it only returns a non-exited
thread.

Rename it to any_non_exited_thread_of_inferior to better reflect its
behavior. This is a preparatory change for the following patch, which
adds another helper with similar semantics.
