Remove subpackage maintainer concept

[seanpmorgan]

Description

The repo maintainers have discussed and we feel that the subpackage maintainer concept has grown stale. Originally we wanted to split subpackages amongst ourselves where small groups of maintainers would serve as the failsafe for given subpackages. In practice this meant every subpackage would have had a very limited amount of people who were ultimately responsible. This created unnecessary stress on maintainers to feel like they were required to keep working on the project in order for the subpackage to remain viable.

Ultimately all write access maintainers can help across the repo and have been doing so for an extended period of time. However, there is an added need for reliable submodule owners which is what we've discovered over the past few months. We'll be working on improving that system through #2024
