Add display light control option for Daikin and Gree climate platforms

- Introduced an optional `display` parameter to control the indoor unit display light, defaulting to `true`.
- Added a tip about the Gree climate platform's custom preset `Light off` for automations.
- Included example configurations for toggling the display light at runtime.

This enhances user control over the display settings for better customization.

+- **display** (*Optional*, boolean): Controls whether the indoor unit display light remains on. Defaults to `true`. Set this to `false` if you prefer the panel light to stay off when ESPHome sends commands. This preference is preserved when switching between the standard presets (for example, `sleep`) that the integration exposes for compatible models.
+
+> [!TIP]
+> The Gree climate platform also exposes a custom preset named `Light off`, which can be used in automations to temporarily disable the display light without changing other preset options. While this preset is active it overrides the `display` setting; once cleared, the display light automatically returns to the configured `display` value.
