lwc:dom="manual" is not enforced on childNode.remove() api

[ravijayaramappa]

Description

lwc:dom="manual" restriction is not enforced when calling remove() api. https://developer.mozilla.org/en-US/docs/Web/API/ChildNode/remove
This is inconsistent behavior because the restriction is enforced on removeChild() api.

Additionally, audit if there are other DOM manipulation APIs that the engine is not enforcing the restriction on.

Steps to Reproduce

<template>
      <div>
             <span></span>
      </div>
<template>

export default class Foo extends LightningElement {
     someMethod() {
          const span = this.template.querySelector('span');
          span.remove(); // Does not throw
          span.parent.removeChild(span); // Will throw an exception because of restriction
     }
}
