Build-in functions are located in the java-exec module. Some are generated using freemarker, some are located in the org.apache.drill.exec.store.hive package. Currently to get full list of the UDFs, you need to turn on trace logging and check the logs [1]. The good news, currently Kunal is working on the sys.functions table implementation which will list all UDFs [2, 3]. Will be available in Apache Drill 1.15.
