eal: rename thread TLS API

Rename the key opaque pointer from rte_tls_key to
rte_thread_key to avoid confusion with transport layer security.

Also rename and remove the "_tls" term from the following
functions to avoid redundancy:

rte_thread_tls_key_create
rte_thread_tls_key_delete
rte_thread_tls_value_set
rte_thread_tls_value_get

    =======================================================
 
+* eal: The experimental TLS API added in ``rte_thread.h`` has been renamed
+  from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy
+  and confusion with the transport layer security term.
