Support setting different UI progress modes

This change adds a flag to select between UI progress modes. The initial
values are oldest_actions and mnemonic_histogram; the latter of these is
also added in this change.

The new mode turned out to be useful for debugging an issue where Bazel
ran out of memory due to a high number of ActionExecutionFunction
Skyframe restarts.
