Finish converting SMTK_PLUGINS from cached var to global property

It looks like smtk plugins in our extensions are still using a global variable SMTK_PLUGINS, and were not updated to using the global property with the same name. This MR removes the global var completely and only uses the global property SMTK_PLUGINS.

@tjcorona it seems that smtk extensions were still using the global/cache variable instead of the global property. This MR changes everything to global property -- does that seem right to you?
