#11344: fixes issue with xy-color mode only devices

[xLerate]

• changed default for hsv-meta attributes to false inside light-color converter (adresses ModernExtend does not respect limited color mode capabilites for light endpoints #11344)
• added hsv->xy color conversion to support devices with xy color mode only, when sent hsv color

The PR looks bigger than it actually is. I had to swap some code blocks.

FYI: converting colors here is useful when Zigbee2MQTT is connected to Matterbridge-Zigbee2MQTT for example, because most Matter controllers (Alexa, Google Home) primarily send HSV colors.

Could you add a test case for this to

zigbee-herdsman-converters/test/toZigbee.test.ts

Line 368 in 3045cfb

describe("light_onoff_brightness", () => {

?

[xLerate]

added two tests for hsv color sent to xy color only device

• xy color mode forced by color: { mode: ["xy"] }
• xy color mode given by color: true (which also defaults to xy color only)
  for both tests the incoming hsv color has to be converted to xy color and sent to the device via moveToColor command.

tests are added in own block (-> "light_color") inside toZigbee.test.ts

I checked this against the z2m tests cases but it makes https://github.com/Koenkk/zigbee2mqtt/blob/3a49c95786c2fba749e7696aab4cc38e467d2c4c/test/extensions/publish.test.ts#L1322 fail:

This test runs against the Philips 7146060PH which uses the default args so it should support ehancedHue:

zigbee-herdsman-converters/src/lib/modernExtend.ts

Line 1190 in e91d091

enhancedHue: true,

Could you check?

[xLerate]

Are supportsHueAndSaturation and supportsEnhancedHue independent of each other. Or does supportsEnhancedHue implies supportsHueAndSaturation, meaning supportsEnhancedHue is as a special case of supportsHueAndSaturation ?

Yes, when supportsEnhancedHue = true, then supportsHueAndSaturation must also be true.
