cleanup: Remove VoxelPrimitive.jitter option (#11913)

[okrayum]

Description

In VoxelPrimitive.js I removed the following code blocks:

/**

• @type {boolean}
• @Private
  */
  this._jitter = false;

/**

• Gets or sets whether or not to jitter the view ray during the raymarch.

• This reduces stair-step artifacts but introduces noise.

• @memberof VoxelPrimitive.prototype

• @type {boolean}
  */
  jitter: {
  get: function () {
  return this._jitter;
  },
  set: function (jitter) {
  //>>includeStart('debug', pragmas.debug);
  Check.typeOf.bool("jitter", jitter);
  //>>includeEnd('debug');

  if (this._jitter !== jitter) {
  this._jitter = jitter;
  this._shaderDirty = true;
  }
  },
  },

In VoxelRenderResources.js I removed the following code block:

if (primitive._jitter) {
shaderBuilder.addDefine("JITTER", undefined, ShaderDestination.FRAGMENT);
}

In VoxelPrimitiveSpec.js I removed the following line from the test "toggles render options that require shader rebuilds":

toggleOption("jitter", false, true);

Testing plan

I ran npm run test prior to making any changes in the codebase and it showed 11 failing tests, I ran it again after making changes and it had the same failing tests. This was all done in the terminal, I then ran the tests through the browser, and it showed one failing test. I'm not sure if that is just in my environment. If they fail in the workflow I may need some additional guidance.
