Deprecate `blacklist`/`whitelist` in favor of `include`/`exclude` (#31569)

For a long time the module configuration has had a few settings that use
`blacklist`/`whitelist` terminology. We've been asked by some of our users to replace
this with more inclusive language. In addition to being non-inclusive, `blacklist` and
`whitelist` are inconsistent with the rest of Spack, which uses `include` and `exclude`
for the same concepts.

- [x] Deprecate `blacklist`, `whitelist`, `blacklist_implicits` and `environment_blacklist`
      in favor of `exclude`, `include`, `exclude_implicits` and `exclude_env_vars` in module
      configuration, to be removed in Spack v0.20.
- [x] Print deprecation warnings if any of the deprecated names are in module config.
- [x] Update tests to test old and new names.
- [x] Update docs.
- [x] Update `spack config update` to fix this automatically, and include a note in the error
      that you can use this command.
