These Kconfig options provided a level of configurability that is
almost never necessary, so they are being moved into ordinary
preprocessor defines in elog_internal.h. The new threshold to
trigger shrinking is relative to the number of additional
(maximum-size) events that can fit, and the new target
post-shrink size is a percentage of the total ELOG area size.
BUG=chromium:467820
TEST=Add loop at the end of elog_init() that fills the ELOG area
to just below full_threshold with dummy events. Observe
successful shrinkage when the next event is logged.
