Unified USD orderbook revamp

To revamp unified USD orderbook, more details for the first type users, more details for the second type users. OKX delisted the Crypto-USDC trading pairs and upgrade the Crypto-USD trading pairs for accessibility to all users.

Users are categorized into two types based on their country or region, with varying solutions for each. If you get valid data from GET /api/v5/account/instruments?instType=SPOT&instId=BTC-USD, you belong to the first type users, if you get an empty array [] data from that URL, you belong to the second type.

Example 1: Placing an order with BTC-USDC:

Type Before upgrading After upgrading
Operation Trading BTC-USDC Trading BTC-USDC
Request fields for "op": "order" First option:
{
     "instId": "BTC-USDC",

    "instId": "BTC-USD",
    "tradeQuoteCcy": "USDC"
}
Only option:

    "tradeQuoteCcy": "USDC"
}
