Port mine command to 1.x

• Cherry-picks command and devnet changes made at c719311 for next/2.0.
• Also extends the command to allow for mining multiple blocks at a time.

As the cli is solely used for devnet, it assumes the provider is foundry/anvil in order to perform that instead of relying on method rpc_modules to discover if amvil_mine can be used instead of a loop of evm_mine calls to achieve the same result.

LGTM, just one question for a possible future issue: since this is the new way to advance the blockchain state, does it make sense to still have the increasetime command? Should we delete it?

You're right, this should be revisited later on.
