Switch LibJS `RegExp` over to the Rust-backed `ECMAScriptRegex` APIs. Route `new RegExp()`, regex literals, and the RegExp builtins through the new compile and exec APIs, and stop re-validating patterns with the deleted C++ parser on the way in. Preserve the observable error behavior by carrying structured compile errors and backtracking-limit failures across the FFI boundary. Cache compiled regex state and named capture metadata on `RegExpObject` in the new representation. Use the new API surface to simplify and speed up the builtin paths too: share `exec_internal`, cache compiled regex pointers, keep the legacy RegExp statics lazy, run global replace through batch `find_all`, and optimize replace, test, split, and String helper paths. Add regression tests for those JavaScript-visible paths.
