Do not expand UMA_HISTOGRAM_ENUMERATION in 19 places.

Instead of expanding UMA_HISTOGRAM_ENUMERATION macro in 19 places, use a
single static method to log this histogram.  The motivation for this
change is to avoid binary bloat.

This is a follow-up to https://crrev.com/c/1055949.

This CL results in 2384 byte decrease in binary size for locally
compiled release build on Linux, and no change for debug build.
