[glibc/fw/libpthread-20210318b] Remove pthread_key_create-related internals from libc-lock.h

commit ebf27210c365fb39980a7e3bf31d7e468dc3ae3b
Author: Florian Weimer <fweimer@redhat.com>
Date:   Tue Mar 16 18:05:39 2021 +0100

    Remove pthread_key_create-related internals from libc-lock.h
    
    And libc-lockP.h.  This is no longer used because all internal
    TLS use goes directly to the thread descriptor/TCB or uses ELF TLS.
