Incorrect default `Origin` value for `Sprite` class

[AristurtleDev]

The Sprite class should have a default origin of (0, 0) to match the default SpriteBatch.Draw origin parameter being the top-left corner. Currently, in the Sprite constructor, OriginNormalized is set to (0.5, 0.5) which is causing the Origin to update to center of the sprite.

This should be set to the default Vector2 value or Vector2.Zero

I think this "fix" from 4.0.4 actually messes up something else.

Either the change in #969 breaks standard sprite handling, or, perhaps it breaks tile map rendering positioning?

Looks like before the Tile was being created in the sample with a half sprite size positive adjustment. Removing this didn't fix the issue but put the player halfway into the tile. Subtracting half instead does fix it.

It feels odd that this is nesesary. MonoGame.Extended-samples\src\Games\Platformer\EntityFactory.cs

Pong is also now broken after 4.0.4. Fixing that also.

I worked around this change in the samples MonoGame-Extended/MonoGame-Extended-Samples#28
