Mexc - Failed to cancel order <order id> appears when partial fills happened

[leetjoy]

Describe the bug

There is an issue observed with MEXC connector, if the order was partially filled and Humming bot canceled it - then it cannot fetch status update on this order.

Failed to cancel order <order id> error appears in log
Error fetching status update for the lost order ... Partially Cancelled

I would appreciate if anyone can fix it.
MEXC is growing exchange and connector deserves to be GOLD :)

Steps to reproduce

1. connect to MEXC
2. using pure_market_making create some orders on any paid
3. wait when one of order will be partially filled and bot will attempt to cancel it
4. -> here comes the error

@rapcmia @fengtality @nikspz I talked with @leetjoy and he wants to fund this bounty. I think that has to be considered as P2 and the solution should include:

• cancel order method --> Review how the order is processed when sending the cancelation. (specially when having partial fills)
• evaluate the solution proposed in this PR https://github.com/hummingbot/hummingbot/pull/6584/files for the methods:
  _is_order_not_found_during_status_update_error
  _is_order_not_found_during_cancelation_error

Once the connector solution is ready we have to validate it by running a bot for > 1 day without issues

Okay, then to validate this as P2 Bounty (50k HBOT) it should be funded with 55k HBOT (50k +10%) or 133USDC (111 USDC +20%) using these wallets:

@nikspz can I fund this bounty by sending USDC from CEX?

@leetjoy For BEP20, 0xE517b826a26B439eCE92f3220628eC007049d915 can be used for USDC.
