Since blockly.mjs is no longer returning just the exports object from core/blockly.js (see PR #5995), it might be better named after its actual purpose: to wait for bootstrapping to be done. Remove all the code that was used to pass the blockly.js exports object along from the bootstrap callback to the blockly.mjs export, since there's no reason to go to a lot of trouble to set a local variable named Blockly to the same value as a global variable named Blockly. (Something like this may be needed again in future, but certainly in a different form.)
