Missing methods on INCOMING_MODULE_JS_API, like `onMalloc`

Please include the following in your bug report:

**Version of emscripten/emsdk:**
3.1.32

CMAKE link options:
```cmake
"SHELL:-s MODULARIZE=1"
"SHELL:-s EXPORT_NAME=${MODULE_NAME}"
"SHELL:-s ENVIRONMENT=web,worker"
"SHELL:-s FETCH=1"
"SHELL:-s DYNAMIC_EXECUTION=0"
"SHELL:-s STRICT=0"
"SHELL:-s IMPORTED_MEMORY=1"
"SHELL:-s --minify 0"
"SHELL:-s --closure 0"
"SHELL:-s INCOMING_MODULE_JS_API=onMalloc" # same with or without
```

Looking at the output .js files, or logging the `Module` object, there are tons of things missing from https://github.com/emscripten-core/emscripten/blob/main/src/settings.js#L951C5-L965.

I'd especially need methods that are related to memory management. Is there any reason why they aren't included?
