Feat: Add Base Pools to GammaSwap (DefiLlama#1267)

* pools yield information for gammaswap

* annualize yield, fix BN to decimal conversion, format USDC bridged symbol from USDC to USDC.e

* adding url per pool

* added borrow apy

* adding IGammaPool ABI to get poolViewer from weth/usdc gammapool in arbitrum, to use in all other calls

* removing unused imports

* add base pools query and filter out odd decimal pools
