[wrangler] fix: make sure getPlatformProxy's ctx methods throw illegal invocation errors like workerd

[dario-piotrowicz]

What this PR solves / how to test

in workerd detaching the waitUntil and passThroughOnException methods from the ExecutionContext
object results in them throwing illegal invocation errors, such as for example:

export default {
	async fetch(_request, _env, { waitUntil }) {
		waitUntil(() => {}); // <-- throws an illegal invocation error
		return new Response("Hello World!");
	},
};

this PR makes sure that the same behavior is applied to the ctx object returned by getPlatformProxy

To test it simply use the prerelease and try destructuring and calling the methods of the getPlatformProxy'sctx object

Note

The same sort of logic would ideally need to be applied to bindings, that however involves the magic proxy so it likely won't be as straightforward as it was here for ctx, thus I thought not to cram both in this PR, so I'll try to do the bindings one in a followup PR (see: #6200)
