[Rust] Update reqwest to 0.13 and reqwest-middleware to 0.5 (#22816)

* [Rust] Update reqwest dependency to 0.13 with query and form features

Update the Rust client generator template to use reqwest 0.13 instead
of 0.12, as requested in issue #22621.

In reqwest 0.13, the `query()` and `form()` methods have been moved
behind feature flags and are disabled by default. Since the generated
Rust clients extensively use both methods, these features must be
explicitly enabled.

Changes:
- Updated all reqwest dependencies from ^0.12 to ^0.13
- Added "query" and "form" to reqwest feature flags for all variants:
  - Blocking client configuration
  - Async client with file stream support
  - Async client without file stream
  - Reqwest-trait variant
- Updated reqwest-middleware features for consistency

This maintains full backward compatibility as only the dependency
version and features change. The API surface of generated code
remains identical.

Fixes #22621

* [Rust] Updated samples

* [Rust] Rename rustls-tls feature to rustls to match reqwest 0.13

In reqwest 0.13, the rustls-tls feature was renamed to rustls.
This updates the Cargo.mustache template and all generated samples
to use the new feature name, fixing CI build failures when using
--all-features flag.

* [Rust] Upgrade reqwest-middleware to 0.5 for reqwest 0.13 compatibility

The previous reqwest-middleware 0.4 depends on reqwest 0.12, which caused
type conflicts when upgrading to reqwest 0.13:
- reqwest::Error (from reqwest 0.13)
- reqwest_middleware::reqwest::Error (from reqwest 0.12 via middleware)

These are different types from different versions of reqwest.

reqwest-middleware 0.5 is compatible with reqwest 0.13, resolving the
version conflict. With both using the same reqwest version, the re-exported
types are now correctly aligned.

* [Rust] Use query and form features from reqwest-middleware

It adds "query" and "form" features for reqwest-middleware crate in petstore-async-middleware example and Cargo.mustache template.
