Add options to enable events in SPL. This is mostly so the code can be
excluded from SPL builds.

+         This adds a framework for general purpose sending and processing of
+         events, to allow interested parties to be alerted when something
+         happens. This is an attempt to stem the flow of weak functions,
+         hooks, functions in board_f.c and board_r.c and the Kconfig options
+         below.

+         Enable this to support adding an event spy at runtime, without adding
+         it to the EVENT_SPY() linker list. This increases code size slightly
+         but provides more flexibility for boards and subsystems that need it.
