Add ECO mode to `midea_ir` presets

**Describe the problem you have/What new integration you would like**

Add the ECO preset to the list of supported presets under `midea_ir`.
**Please describe your use case for this integration and alternatives you've tried:**

When configuring the `midea_ir` platform the climate presets don't include the ECO mode.
**Additional context**

Similar to the TURBO command it should be possible to set the preset to ECO. I have searched for the ir commands for both presets and found as follows:
Turbo: B5 F5 A2
Eco : B5 F5 82

When I tried reading the ECO button from the remote control I am getting:
Toshiba AC: rc_code_1=0xB54AF50A8240 / Samsung: data=0xB54AF50A8240, nbits=48

I am not sure how to implement this in the existing code. I can see that `TURBO_TOGGLE = 9`. So what would the value for ECO_TOGGLE in this case.

Start by locating the midea_ir preset definitions and the existing TURBO_TOGGLE value. Verify how the reported ECO command maps to the integration's preset handling; done means ECO is available as a selectable climate preset and the relevant behavior is covered by the project's existing checks.
