Subject: [PATCH] [Python O11Y] Fix core header dependency issue (#35845)

Core team [moved resolver code](https://github.com/grpc/grpc/pull/35804) to `src/core/resolver`, our build is failing because we have a dependency on it and the resolver folder is not copied to `observability/grpc_root`:
 * `call_tracer.h` -> `core_configuration.h` -> `lb_policy_registry.h` -> `lb_policy.h` -> `endpoint_addresses.h`

To fix this issue and to prevent such issues from happening again, instead of subfolders, we'll copy all files from `src/core` to `observability/grpc_root/src/core`.
