chore(bridge-controller): faster utils

[Nodonisko]

Explanation

While working on https://github.com/MetaMask/metamask-mobile/pull/22744 I noticed that if do this small change of pre-converting values I can save up to 25% of time when looping though big array of tokens where this functions were used multiple times per one loop.

[!NOTE] Precomputes chain ID string constants and uses them in isSolanaChainId, isBitcoinChainId, and isTronChainId within utils/bridge.ts.

• utils/bridge.ts:
  • Add constants: SOLANA_MAINNET_CHAIN_ID_STRING, SOLANA_CHAIN_ID_STRING, BITCOIN_MAINNET_CHAIN_ID_STRING, BITCOIN_CHAIN_ID_STRING, TRON_MAINNET_CHAIN_ID_STRING, TRON_CHAIN_ID_STRING.
  • Update isSolanaChainId, isBitcoinChainId, isTronChainId to compare against precomputed strings instead of inline toString() calls.
