(Java Parity) 64-bit calculations

64-bit calculations are great for Bedrock for reasons, as mobile phones and computers are generally more powerful than the past:

• The Stripe Lands won’t have to generate at 30 million blocks at the origin.
• Less distance effects at higher distances.
• Avoids non-solid solid blocks to the player at over 9 million blocks from the world origin.
• Stops issues falling through the world at over 9 million blocks from the world origin.
• Exploring more of the world is possible.
• The floating-point should be raised to 64-bit.
• Less jitter at higher distances.

Considerations:

• Many old devices will have to be discontinued, but that means more focus for Mojang on the game.
• Some weak devices cannot run Minecraft unless support drops.
