[logger] Add log file rotation by options to logger_std_h

OTP-15479
OTP-15662

New configuration map for logger_std_h:

 #{type => file,
   file => file:filename(),
   modes => [file:mode()],
   max_no_bytes => pos_integer() | infinity,
   max_no_files => non_neg_integer(),
   compress_on_rotate => boolean()}

For backwards compatibility, the old variant for specifying the file
name via the 'type' parameter is still supported, i.e. {file,FileName}
and {file,FileName,Modes}, but it is no longer documented.

Rotation scheme:
The current log file always has the same name, and the archived files
get extensions ".0", ".1", ... The newest archive has extension ".0",
and the oldest archive has the highest number.

If 'compress_on_rotate' is set to true, the archived files are gzipped
and get the additional extension ".gz", e.g. error.log.0.gz.

Rotation is turned off by setting 'max_no_bytes' to infinity. Setting
'max_no_files' to 0 does not turn off rotation, but only specifies
that no archives are to be saved.
