Initial License Checkin

This patch adds license information for about 5,300 packages from automated sources.
The license information was obtained from Alpine Linux and PyPI and processed
using tooling available in https://github.com/boomanaiden154/spack-license-utils.
The license field was added in after all other directives in an automated fashion.

Note that while this license information is probably fairly accurate, it is not
guaranteed to be accurate. In addition some of the license strings from Alpine Linux
might not be valid SPDX license strings. Invalid SPDX identifiers can be picked up
and fixed once we have validation/parsing infrastructure in place for the solver,
and issues can be fixed as they come up.
