Adds LOG_TAG to cpp files not including it already

Adds missing LOG_TAG to non-test files.
Files under driver/cache/ have the LOG_TAG set at build time and
I didn't want to alter that. It could also have been an option
for all operations but that would have required some restructuring of
the build. Created issue b/136627182 to track this.
