[CommandLineParser] Add DefaultOption flag

Description

[CommandLineParser] Add DefaultOption flag

Summary: Add DefaultOption flag to CommandLineParser which provides a
default option or alias, but allows users to override it for some
other purpose as needed.

Also, add -h as a default alias to -help, which can be seamlessly
overridden by applications like llvm-objdump and llvm-readobj which
use -h as an alias for other options.

(relanding after revert, r358414)
Added DefaultOptions.clear() to reset().
