Remove PhotonJNICommon in favor of CombinedRuntimeLoader (#2223)

## Description

PhotonJNICommon is just our implementation of combined runtime loader,
which we don't really need. This removes it and just uses
CombinedRuntimeLoader directly. This also fixes the issues introduced in
#2219, which lead to some of our JNIs not loading.

## Meta

Merge checklist:
- [x] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [x] The description documents the _what_ and _why_
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with settings back to v2025.3.2
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [x] If this PR addresses a bug, a regression test for it is added
