Series static_call: make selftest available for out-of-line SC |

Commit Message

Song Shuai Jan. 10, 2024, 10:48 a.m. UTC 
  Static call selftest should be built once HAVE_STATIC_CALL is configured.
but it's now bonded with HAVE_STATIC_CALL_INLINE.

Move selftest to static_call.c making it available for out-of-line SC.
