[java] Adding native library loader to SessionOptions and RunOptions static init

[Craigacp]

Description

Unlike most ORT classes SessionOptions and RunOptions don't trigger native library loading of the JNI binding and ORT when the classes are initialized (after class loading). This was initially because I thought that loading an inner class would trigger the static initialization of the outer class, but this is not true. So if you create a SessionOptions instance before referencing OrtEnvironment then you won't trigger library loading and you'll get an error saying it couldn't link the native method that creates a SessionOptions object.

Note this doesn't prevent users from creating a SessionOptions and modifying it before the OrtEnvironment is created, which can still cause issues. It would be a breaking API change to modify the SessionOptions constructor to take an environment, and it wouldn't mirror the way it works in the C API which requires this by convention rather than API design, but we can discuss making that modification later.

Motivation and Context

Reduces the occurrence of mysterious Java library loading errors. Helps with #16434.

I think it's safe to squash and merge, the 1 failing test doesn't have anything to do with your changes.

Sounds good. Would you mind having a look at #16198 as well? That one is a bit more involved, but we'd really like to have better support for loading in large models without the filesystem from Java so I needed to add a few new native accessors.

Yep, will take a look
