Cleanup prepare_call_env function

[mattsse]

Describe the feature

this currently accepts a gas limit field:

reth/crates/rpc/rpc-eth-api/src/helpers/call.rs

Line 1102 in f1aae36

gas_limit: u64,

however we only call this with the configured call gas limit:

reth/crates/rpc/rpc-eth-api/src/helpers/call.rs

Lines 448 to 451 in f1aae36

	/// Returns default gas limit to use for `eth_call` and tracing RPC methods.
	///
	/// Data access in default trait method implementations.
	fn call_gas_limit(&self) -> u64;

so this arg is kinda pointless.

also we should not disable gas_limit, because that's an anvil relict where this is safe.

TODO:

• remove gas_limit arg
• remove disable gas_limit setting
