Being able to not "echo" Cleaning, Generating, Writing when using 'QUIET'
https://github.com/Dav1dde/glad/blob/01277173613cdb0339f58de9f6d090474ddbeab2/cmake/GladConfig.cmake#L242

In the GladConfig.cmake file, there should be a flag that can be set by the user to not 'echo' these info when using the 'QUIET' mode:
- Cleaning ... 
- Generating ...
- Writing ...

Also, there should be a flag allowing not to produce the 'args.txt' 

In the case a user would like a Quiet build (like myself), there are still messages outputing to the console. There should not be.
