Add language dependencies `c`, `cxx`, and `fortran`.
These `depends_on` statements are auto-generated based on file extensions found

The `# generated` comment can be removed by package maintainers after

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.
Explicitly import package utilities in all packages, and corresponding fallout.
This includes:
* rename `spack.package` to `spack.package_base`
* rename `spack.pkgkit` to `spack.package`
* update all packages in builtin, builtin_mock and tutorials to include `from spack.package import *`
* update spack style
* ensure packages include the import
* automatically add the new import and remove any/all imports of `spack` and `spack.pkgkit`
from packages when using `--fix`
* add support for type-checking packages with mypy when SPACK_MYPY_CHECK_PACKAGES
is set in the environment
* fix all type checking errors in packages in spack upstream
* update spack create to include the new imports
* update spack repo to inject the new import, injection persists to allow for a deprecation period
Original message below:
As requested @adamjstewart, update all packages to use pkgkit. I ended up using isort to do this,
so repro is easy:
```console
$ isort -a 'from spack.pkgkit import *' --rm 'spack' ./var/spack/repos/builtin/packages/*/package.py
$ spack style --fix
```
There were several line spacing fixups caused either by space manipulation in isort or by packages
that haven't been touched since we added requirements, but there are no functional changes in here.
* [x] add config to isort to make sure this is maintained going forward
