Feature #12224: logger: Allow specifying log level in constructor

----------------------------------------
When I use Logger class, I very often (or maybe always) set minimal log level together. Since method chaining can't be used for setters, we have to split it into two statements:

~~~ruby
logger = Logger.new($stdout)
logger.level = :info
~~~

Imagine if the `logger` was much longer name, such as ActiveRecord::Base.logger. I personally don't want to repeat it.
I found a number of samples on GitHub (they would countain copy-and-pastes though) [1].

So I propose adding a new keyword argument `level` to Logger.new:

~~~ruby
logger = Logger.new($stdout, level: :info)
~~~

This will be effectively same as the original code I indicated above.

I attached a patch for this.
