feat(sidekick/rust): decouple option extraction and support resource names (roll-forward)

[haphungw]

Roll forward the resource name generation logic by constructing ResourceNameTemplate and ResourceNameArgs individually for each PathBinding, for services with resource_name option enabled.

Also remove obsolete fields (ResourceNameTemplate and ResourceNameArgs), nest options properly (detailed_tracing_attributes and resource_name), and repair formatted spacing.

Fixes #4183

Code Review

This pull request refactors the resource name generation logic for the Rust sidekick, decoupling it to operate on a per-PathBinding basis. This is a good architectural improvement that makes the logic more modular and easier to follow. The changes are consistently applied across the Go annotation code, the tests, and the Rust templates. The tests have been updated effectively to cover the new per-binding logic. I have one suggestion to improve maintainability by removing some fields from the method-level annotation that appear to have become obsolete with this refactoring.

The results in googleapis/google-cloud-rust#4936 look good for DNS. If you only enable DNS, and remove the extra blank lines, I think you can submit this and then work on the small bug I noticed in that PR.
