Cleanup upstreamed patches & fix angular

[t2t2]

Description

Issues with angular: https://codesandbox.io/s/angular-material-tooltip-fhimx?file=/src/index.html

1. Tooltip location isn't properly updated as while it waits for ngzone's microtask queue to flush out, the microtask never existed due to us patching Node (as a fix for IE not having EventTarget) vs zone patching EventTarget or Node depending on browser support. Node is before EventTarget in prototype chain so even though zone patches addEventListener later, it will never get called as Node's addEventListener is found first.

   Upstreamed version of the IE fix matches zone's patching = doesn't cause this issue, so fixing by removing our version of the fix.

2. After angular gets to use zone again there's an issue with passive event listener feature detection where null event listener doesn't work as a key in weakmap used in otel code (TypeError: Invalid value used as weak map key)

   Added a quick check for non-values to addPatchedListener.

   Otel doesn't have this issue as it uses zone for event listener tracing if possible. But it's still worth pr-ing a fix to otel, probably should also check other "fun" ways to make event listeners (I think you can pass a string as a listener too, calling the global function with that name? That's also not valid for weakmap)
