Rework Experience System

I believe the current experience system should be reworked in Minecraft. It's currently a messy, unintuitive and frustrating system that players are forced to get used to to get better at the game. Here are some thoughts that would make obtaining and using experience more entertaining:

- Animals should always drop 2 EXP instead of randomly between 0-3;
- Monsters should have more varying experience drops depending on how strong they are. Endermen, creepers, ghasts, hoglins and witches should drop 10 EXP instead of the usual 5. The Wither should drop 1000 EXP the first time it is killed in the world, similarly to how the Ender Dragon drops more EXP the first time;
- Obtaining ores should have the same amount of EXP drops regardless of the way it is done. This means coal drops the usual amount even when mined with silk touch and then smelted, for example;
- Killing mobs in unexplored chunks should yield a bonus EXP to reward players venturing out;
- Dying should always drop 50% of your EXP instead of capping at LVL 7;
- Anvils should be reworked to be more consistent: Placing the item at the first or second slot should be interchangable instead of changing the price of the enchantment. A new stronger version of anvil should exist to merge very expensive enchantments instead of relying on the enchantment's table RNG;
- It should be possible to refresh enchantment table's enchantments without having to actually enchant anything;
- Bottles of enchanting should always drop 8 EXP.
