Add GN output prefix override and allow empty output extensions.

Previously setting the output extension to an empty string would give the
default extension. This patch differentiates unset (default extension) from
set-to-empty-string (which can now mean "no extension").

A flag is added to out-out of the target output prefix application for targets
that don't want to have "lib" at the beginning on Posix systems. Even though
the flag might more naturally be called "override_output_prefix" I called it
"output_prefix_override" so that all of the output-name-related variables are
called "output_....".
