Merge #15266: memory: Construct globals on first use

Browse Source 
77777c5624 log: Construct global logger on first use (MarcoFalke)

Pull request description:

  The (de)initialization order is not well defined in C++, so generally it is not safe to use globals as the (de/con)structor of one global could use the (de/con)structor of another global before/after it has been (con/de)structed.

  Specifically this fixes:
  * `g_logger` might not be initialized on the first use, so do that. (Fixes #15111)
