dynamicRequire causes runtime issues when bundled with webpack

[timfish]

Which SDK are you using?

@sentry/node

SDK Version

lastest

Steps to Reproduce

This code was added to fix webpack build errors in node < v12

sentry-javascript/packages/node/src/integrations/anr/index.ts

Lines 25 to 31 in 4f92ff0

	/**
	* We need to use dynamicRequire because worker_threads is not available in node < v12 and webpack error will when
	* targeting those versions
	*/
	function getWorkerThreads(): WorkerThreads {
	return dynamicRequire(module, 'worker_threads');
	}

Unfortunatly this causes runtime issues:
getsentry/sentry-electron#828

Expected Result

Should not error

Actual Result

This can just be removed for the next major since we only support Node versions where worker_threads is available
