[cherry-pick][rpc][bugfix] Remove the usage of get_past_object_read f…

…rom get_coin_… (#11999)

…metadata (#11971)

## Description 

The current implementation of `get_coin_metadata` relies on
`get_past_object_read`, which stops working if the fullnode has pruning
enabled. This is unnecessary because we only need the latest version of
the coinmetada object(if it is wrapped, then it's okay to return null).

## Test Plan 

tested locally

```
curl --location 'https://mainnet.sui.rpcpool.com' \
--header 'Content-Type: application/json' \
--data '{
    "jsonrpc":"2.0",
    "id":1,
    "method":"suix_getCoinMetadata",
    "params":["0x2::sui::SUI"]
}'
```

```
{
    "jsonrpc": "2.0",
    "result": {
        "decimals": 9,
        "name": "Sui",
        "symbol": "SUI",
        "description": "",
        "iconUrl": null,
        "id": "0x9258181f5ceac8dbffb7030890243caed69a9599d2886d957a9cb7656af3bdb3"
    },
    "id": 1
}
