Add proper Off-hand feature to Minecraft Bedrock Edition

Please add the Off-hand feature to Minecraft Bedrock Edition, at least for holding items (held slot). It should work for weapons, tools, and armor stand. In Bedrock Mobile, we don't necessarily need a new action button, just make it work like in Java where we can put items in the offhand slot from inventory. Here is the main reason why this is very important: We have tools like Hoe with Mending enchantment. The durability of a hoe is very low and breaks easily. Right now in Bedrock, to make Mending work and restore its durability, we are forced to hold the hoe in our hand. But if we go to a mob farm, holding a hoe to hit mobs is very slow and not efficient. It would be much better if we can hold the hoe + mending in our LEFT HAND (offhand), while holding a strong SWORD with Sharpness and Looting in our RIGHT HAND (main hand). By doing this, the hoe will still get XP orbs and its durability will restore automatically, while we can kill mobs fast and efficiently using the sword. Instead of holding the hoe directly and hitting mobs with it (which feels bad and slow), using the sword is way better and the Mending effect still works on the tool in offhand.
