rust: opp: Move `cfg(CONFIG_OF)` attribute to the top of doc test

2025-05-27T13:29:17Z

Move the `#[cfg(CONFIG_OF)]` attribute to the top of the documentation test block and hide it. This applies the condition to the entire test and improves readability. Placing configuration flags like `CONFIG_OF` at the top serves as a clear indicator of the conditions under which the example is valid, effectively acting like configuration metadata for the example itself.

rust: opp: Make the doctest example depend on CONFIG_OF

2025-05-26T11:07:23Z

The doctest example uses a function only available for CONFIG_OF and so the build with doc tests fails when it isn't enabled. error[E0599]: no function or associated item named `from_of_cpumask` found for struct `rust_doctest_kernel_alloc_kbox_rs_4::kernel::opp::Table` in the current scope Fix this by making the doctest depend on CONFIG_OF.
