[New manufacturer : Yokis] Add support for several Yokis devices

[LaurentChardin]

Disclaimer : i do not represent Yokis company, but i was in contact with them to help add support for their devices into Zigbee2Mqtt. This is still a work in progress but the current status is very functional already.

This PR is the first iteration to provide support for Yokis products:

• Declare Yokis custom clusters
• Provide default checks for some attributes
• Use of ModernExtend exclusively

Some clusters are declared but not implemented, as some documentation is still pending and additional tests are required.

List of devices:

• MTR500E-UP
• MTR1300E-UP
• MTR2000E-UP
• MTV300E-UP
• MVR500E-UP
• E2BP-UP / E2BPA-UP
• E4BP-UP / E4BPA-UP / E4BPX-UP
• TLC1-UP
• TLC2-UP
• TLC4-UP
• TLC8-UP
• TLM1-UP / TLM503-UP
• TLM2-UP / TLM2_503-UP
• TLM4-UP / TLM4_503-UP
• GALET4-UP

Another PR will be submitted to the documentation site shortly.

• Most documented features for MTV300E-UP are not available. Can we keep only the implemented ones ? Currently it may lead to the purchase of devices one might regret.
• Most basic/primary feature of the MTV300E-UP, setting the brightness, is not working correctly when the value is set around 100. It has been documented here : YOKIS MTV300E-UP cannot set brightness zigbee2mqtt#25841
• Thank you for your contribution
