Define a proto file that generates the current build completion status.
Soong UI will generate a new proto file in the out directory for
other systems to read the build completion status during a course
of a build. The proto file contains build action counters where
total_actions: represents the total build actions of a build (will
increase and may decrease during a course of the build)
finished_actions: represents the number of executed build actions.
finished_actions never decreases and finished_actions <= total_actions.
current_actions: represents the number of build actions being executed
and current_actions + finished_actions <= total_actions.
