Browser library listener API method logging makes log.html too noisy

[aaltat]

Describe the bug
Library logs stuff with listener API quite a lot of stuff at debug or info level. It makes the log.html quite messy and harder to read with Robot Framework 7.2 (This is new feature of RF 7.2, in the past logging was only visible in the syslog.)

• Go trough the logging and remove which is not needed
• When logging is needed, it should not happen in info level. Also debug level might be too much. Move logging to trace level.
• Think should more logging be added, most likely not.
