Allow Unicode extended escapes in ES5 and earlier (#50918)

* Remove language version check for extended escapes. * Accepted baselines. * Record whether nodes have extended Unicode escapes. Replace them in the es2015 transform. * Accepted baselines. * Move file to better-reflect generality of tests. * Added tests for variables at the top level. * Accepted baselines. * Added test for extended astral character. * Accepted baseline. * Enable sourcemaps in tests. * Accepted baselines. * Call `setOriginalNode` on identifiers with extended escapes.
