[PR] refactor: convert grails-web-url-mappings to Groovy [grails-core]

borinquenkid opened a new pull request, #16603:
URL: https://github.com/apache/grails-core/pull/16603

   ## What
   
   Converts the remaining Java sources of `grails-web-url-mappings` to Groovy: 31 `.java` files removed, 31 `.groovy` files added (38 files changed, 3626 insertions(+), 3678 deletions(-)).
   
   ## Why
   
   The maintainers asked on #16351 for the Java-to-Groovy migration to land one Gradle project at a time as a stack of PRs, bottom-up in dependency order. #16572 did `grails-data-hibernate7`; this PR is 21 of 30 in the next stack (base: `refactor/java-to-groovy-web-databinding-taglib`). The end state of every file is taken from the `9.0.x-java-to-groovy` branch, which already carries the regression fixes found by CI.

   ## Changed outside the converted sources
   
   - nothing
   
   ## Java-facing API sweep
   
   Every deleted `.java` was compared with its Groovy twin via `javap -v -protected` (class declaration, public/protected fields, constructors, methods incl. modifiers/throws/generics, interface default methods, nested class modifiers, and the annotations callers see). Result:
   
   - `grails-web-url-mappings`: 31 deleted .java, 0 differences requiring action
   
   See also the notes below. Remaining informational entries (widened visibility, e.g. Groovy property accessors): 2.
   
   ## Verification
   
   - `classes` and `testClasses` (plus `ast`/`cli`/`testFixtures` source sets where present) of the converted project(s) and of their direct dependents compile: ['grails-gsp', 'grails-gsp-spring-boot', 'grails-mail', 'grails-openapi', 'grails-spring-security', 'grails-spring-security-rest', 'grails-testing-support-views-gson', 'grails-views-core', 'grails-views-markup', 'grails-web-core', 'grails-web-mvc']
   - No test suites were run locally (the umbrella branch was verified; CI runs them). `codeStyle`, `rat` and a whole-repo `build -PskipTests` are run once on the tip of the stack.
   
   ## Notes
   
   - Informational sweep entries that are not regressions: Groovy enums gain `MIN_VALUE`/`MAX_VALUE`/`next()`/`previous()`, property accessors appear for formerly package-private members, nested static classes with implicit constructors become public (they were `protected`), and generic type parameters that Groovy erases in constructors/methods (descriptors identical).
   - Groovy gotchas that applied (see #16351): `static final` without `public` creates a property; `==` calls `equals()`; Closure/SAM coercions; `@CompileStatic` with nested classes. All CI regression fixes found on the umbrella branch are included in the end state.
