David Ormsbee 2568a4280b Reduce size of the commons.js bundle.
Increase the number of bundles that a chunk has to appear in to be put
into the commons.js bundle. This drastically reduces the size of the
commons.js bundle (used basically everywhere on LMS and Studio) from
953K to 188K, mostly at the cost of making AccessibilityPage and
AssetsPage (both Studio-only) larger -- 345K -> 1.1M, 91K -> 865K.
