Clemens Backes 435c5d7a96 [wasm][fuzzer] Use a consistent namespace
Most wasm fuzzers live in the v8::internal::wasm::fuzzer namespace.
Thus also move the wasm-fuzzer there. Additionally
- use the C++20 syntax for declaring the namespace,
- skip unneeded full or partial classifications on types, and
- remove a redundant HandleScope.
