python: specify packages to install for each module (#1246)

### Changelog
- Fixed: python packages `mcap`, `mcap-protobuf-support`,
`mcap-ros1-support`, `mcap-ros2-support` now only install their main
packages rather than all packages including tests.
- Fixed: Add type annotations to `__init__` methods with no arguments
implementing this guide:

### Docs

<!-- Link to a Docs PR, tracking ticket in Linear, OR write "None" if no
documentation changes are needed. -->

### Description

Rely on setuptools' auto-discovery mechanism to find the python packages
we're trying to expose while auto-excluding `tests`, which were
previously being included into users' install directories.

### Testing
- Inspected wheel contents using `python -m zipfile --list
mcap_protobuf_support-0.5.2-py3-none-any.whl` to ensure that the whole
library content is present and no test directories are present.
