[Enhancement] Enable Pyth price feeding for SOLANA Token Economy

[cloud8little]

Most SOLANA tokens are feeded price by pyth, so if we are going to support SOLANA client chain, we would introduce pyth to feed the token price.

Yes, we should integrate Pyth’s price feed, because it supports most asset price feeds on non-EVM chains. We can get more information from its official website (https://www.pyth.network/).
