[Feature] Allow users to change the gas limit for eth_call

[0xDones]

Description

Description

The gas limit for eth_call is currently hard coded in the code. This is preventing Graph Node to index Polygon Edge networks. I'm running a zero gas L2 chain and Graph Node is causing a lot of errors on the RPC node, because the gas limit for this call on Edge should be zero.

Ref:

• "gas limit reached in the pool" #3881
• err="gas limit reached in the pool" 0xPolygon/polygon-edge#2039

• graph-node/chain/ethereum/src/runtime/runtime_adapter.rs

  Line 37 in 139f314

  const ETH_CALL_GAS: u32 = 50_000_000;
