Turn Pancakeswap into a multi-chain DEX

PancakeSwap is probably the best DEX in the entire crypto-space, however, in order to keep growing, it needs to attract more users. The price of the token will only increase if the demand for it is greater, the burning of tokens is not enough to increase the price, so the demand for Cake must be increased. For this we propose to extend the operation of PancakeSwap to multiple blockchains (Polygon, Polkadot, Moonbeam, or others), maintaining the supply, but sharing it between different chains.
