Fixes #5635.

Computed static field names were converted to property keys during static initialization, after later instance field keys and earlier static initializers. The class-name binding was also initialized before computed names were evaluated.

This change converts each static computed name to a key at its source position and initializes the class binding after the element loop, before static initializers run, following ClassDefinitionEvaluation. The later redundant key conversion for anonymous static field initializers is removed.

Five tests cover mixed method/static/instance key order, key conversion before initializers, abrupt key conversion, the class-name TDZ in declarations and named expressions, and class-name access from static and instance initializers.

Validation at ace614acc17106f8d8633b0b1071991506583433, based on 329e89748ed34e218fe593b4209b1dbe1d6eb64d, with Rust/Cargo 1.99.1:

• Four new regression tests failed with unchanged production code; all 17 focused class tests pass with the fix. The TDZ assertion checks the existing C is not defined diagnostic and ReferenceError kind.
• cargo test --locked --profile ci -p boa_engine --lib -- --nocapture --test-threads=1: 1,144 passed, no failures or ignored tests.
• cargo test --locked --profile ci -p insta-bytecode -- --nocapture --test-threads=1: bytecode snapshots passed without updates.
• cargo fmt --all --check: passed.
• cargo clippy --locked --profile ci -p boa_engine --all-features --all-targets -- -D warnings: passed.
• cargo run --locked --profile ci --bin boa_tester -- run -vv -d --test262-path <pinned-checkout> -s <suite> -o <results> for test/language/statements/class and test/language/expressions/class: 8,402 passed, 24 ignored, zero failures/panics on both baseline and candidate, with no case-level outcome changes. Test262 revision: d86b2294eb0a17eaa281ff12c73c473ec864c72f. These existing suites also pass on the buggy baseline; the new unit tests establish the regressions.

Full workspace/all-feature test suites and full Test262 were not run locally. Cargo.lock is unchanged.
