Do not export the numerous Emscripten HEAPxy symbols and remove the last remaining JS code which references them. They have long-since been replaced by internal equivalents and a specific feature check on one of them (which is also no longer needed) is triggering an exception from Emscripten. More details are in [ https://github.com/emscripten-core/emscripten/issues/24656 | Emscripten ticket #24656 ], noting that this is not an Emscripten bug but an Emscripten behavior change brought it to light.
