[py] improve driver logging

[titusfortner]

Description

• Deprecate the current log_file or log_path Service class constructor parameters, which only accepts strings as filenames
• Create new log_output (which matches Java's withLogOutput()) constructor parameter. This parameter that accepts:
  • String for name of file to create (so just like the current methods)
  • TextIOWrapper as an already open file (addresses [🐛 Bug]: PySelenium doesn't support a named pipe as a log file #10703)
  • int (for explicitly specifying subprocess.STDOUT or subprocess.DEVNULL)
• Default for Firefox is now null output instead of geckodriver.log ([🚀 Feature]: Default All Driver Log Output to dev/null #12016)
• If log file selected, Chromium and IE now pipe the whole process output to a file rather than using driver argument (this matches what Java and Ruby do, and captures all driver related output which is nice)
  • EXCEPT - if --append-log or --readable-timestamp are passed (chromium) because those only work with log-file driver argument
• Safari - quiet parameter does not do anything in Apple's driver; it was never removed from prior implementation

Motivation and Context

Make things consistent between drivers and with Java & Ruby

One thing I'm not sure of....
This currently deprecates and warns about the change in default Firefox behavior; I think I'd prefer just changing it and maybe logging a message about the change with a link to the docs (https://www.selenium.dev/documentation/webdriver/drivers/service/#setting-log-output)

Also, I'm not sure I have the typing exactly right? I'm not sure what typing.IO[typing.Any] actually includes.

Thank you, @titusfortner!

Thanks for implementing this!
As this got merged in the 4.11 merge window, will it get released on July 21? And are there any beta/preview/nightly artifacts published somewhere to use this immediately?

@vringar take a look at #12207
