Add file configuration ComponentProvider support for resources

[jack-berg]

Related to #6574.

In the issue, I said this about resources:

For resources, should likely add support for ResourceProvider instead of loading via ComponentProvider since ResourceDeteector is already a first class concept in the specification, and ResourceProvider is the java implementation of ResourceDetector.

I had a change of heart in the implementation. Implementations of ResourceProvider expect to be participating in a configuration scenario which is based on the env var / system property configuration scheme. They receive a ConfigProperties instead of the StructuredConfigProperties used in file config, and look for things in it like otel.resource.attributes and otel.service.name to influence their behavior.

Instead, in this PR I use ComponentProvider to provide resource attributes. This will require me to go and update the various resource provider artifacts and implement ComponentProvider, but will be more precise, and more consistent with the clean separation approach we've been taking with file configuration.
