fix: call evmExecute with gas tokens, Solana improvements

[fadeev]

• Fixed a bug when withdrawing and calling, evmExecute was called without gas tokens, so this broke for example universal NFT/FT, when EVM onCall expected to get tokens: https://github.com/zeta-chain/standard-contracts/blob/32d34c73083882e32389679e0f2228fe2facd4a3/contracts/token/contracts/evm/UniversalTokenCore.sol#L166-L170
• Add mnemonic optional arg to Solana tasks
• Added Solana to CI
• Solana setup:
  • generate a key in ~/.config/solana/id.json if it doesn't exist (otherwise solana program deploy complains)
  • Airdrop to the default user.
• added yarn localnet command to build and run localnet
• Solana deposit/deposit and call import IDL correctly from this npm package

Both Sui and Solana right now are using the same mnemonic for a default user. In both networks, default user gets tokens from the faucet. We'll need to refactor this to allow proper config for default users.

Using this version in zeta-chain/example-contracts#232
