Add extern for goog. (#3417)

As of closure-compiler-v20191027.jar the compile now breaks due to a lack of ‘goog’ being defined. ../../temp_core/constants.js:24: ERROR - [JSC_UNDEFINED_VARIABLE] variable goog is undeclared goog.provide('Blockly.constants'); ^^^^ 1 error(s), 0 warning(s) Compiler exit code: 1 Compilation FAIL. Upgrade closure compiler to v20191027
