installer: Support showing status information in terminal title (#16259)

Browse Source 
Installing packages with a lot of dependencies does not have an easy way
of judging the current progress (apart from running `spack spec -I pkg`
in another terminal). This change allows Spack to update the terminal's
title with status information, including its current progress as well as
information about the current and total number of packages.

By setting this option to ``true``, Spack will update the terminal's title to
provide information about its current progress as well as the current and
total package numbers.
To work properly, this requires your terminal to reset its title after
Spack has finished its work, otherwise Spack's status information will
remain in the terminal's title indefinitely. Most terminals should already
be set up this way and clear Spack's status information.
