Remove ttfb_timeout and resp_timeout (#7925)

`TTFB_TIMEOUT` was deprecated in https://github.com/ethereum/consensus-specs/pull/3767.


  Remove `ttfb_timeout` from `InboundUpgrade` and other related structs.

(Update)
Also removed `resp_timeout` and also removed the `NetworkParams` struct since its fields are no longer used. https://github.com/sigp/lighthouse/pull/7925#issuecomment-3226886352
