Describe the bug
These are forEach from DOMTokenList and NodeList:

• thisArg should be of type any.
• the third argument of callback should be this, not an internal array.

https://github.com/capricorn86/happy-dom/blob/v18.0.1/packages/happy-dom/src/dom/DOMTokenList.ts#L226-L231
https://github.com/capricorn86/happy-dom/blob/v18.0.1/packages/happy-dom/src/nodes/node/NodeList.ts#L200C9-L205

These are forEach from Headers and FormData:

• should accept thisArg?: any

https://github.com/capricorn86/happy-dom/blob/v18.0.1/packages/happy-dom/src/fetch/Headers.ts#L119-L123
https://github.com/capricorn86/happy-dom/blob/v18.0.1/packages/happy-dom/src/form-data/FormData.ts#L93-L97

To Reproduce

// node
const {FormData} = require('happy-dom')
var d = new FormData()
d.append('a', 'b')
const {strict: assert} = require('assert')
d.forEach(function(v, k, t) { console.log(this, v, k, t) }, {foo: 'foo'})
// FormData {} b a FormData {}
d.forEach(function(v, k, t) { assert.equal(this.foo, 'foo'); assert.equal(v, 'b'); assert.equal(k, 'a'); assert.equal(t, d); }, {foo: 'foo'})
// Uncaught AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
//   undefined !== 'foo'

Expected behavior
forEach should work in the same way as Array.prototype.forEach or Map.prototype.forEach.

References to Web IDL spec. There are 3 definitions of forEach depending on the kind of interface but they are essentially the same
