s/require/define/ in a few more files

closes: CNVS-36299

This change makes it so they
Don’t load their deps in a separate chunk so there
is not 2 round trips to get each. RequireJS would bundle
them into one file but webpack treats an amd require([]...
as a split point, different from an amd define([]...

Test plan:
* Run webpack
* you should see less unnamed, numbered chunks
