perf(deps): unify duplicate Rust dependencies to reduce binary size

[intellild]

Summary

• update the lockfile so the url -> idna -> idna_adapter dependency path uses idna_adapter 1.2.1
• remove the duplicate ICU 1.5.x dependency graph from Cargo.lock
• keep ICU-related crates unified on the existing 2.1.x graph used by SWC regexp support
• update the workspace wasmparser dependency from 0.222.0 to 0.235.0
• remove the duplicate wasmparser 0.222.0 entry from Cargo.lock
• remove the now-unneeded icu_normalizer and wasmparser duplicate-dependency skips from deny.toml

Root Cause

idna_adapter 1.2.0 still resolved to icu_normalizer/icu_properties 1.5.x, while swc_ecma_compat_regexp already used icu_properties 2.1.x. Updating idna_adapter allowed Cargo to resolve both paths through the same ICU 2.1.x family.

rspack_plugin_wasm still used workspace wasmparser 0.222.0, while the Wasmtime dependency graph already used 0.235.0. Updating the workspace dependency lets Cargo use the same wasmparser version for both paths, so the cargo-deny skip is no longer needed.

Validation

• cargo tree -i icu_provider shows only icu_provider v2.1.1
• cargo tree -d | grep -E "^icu_| icu_|^idna_adapter| idna_adapter"
• cargo check -p rspack_javascript_compiler --locked
• cargo check -p rspack_plugin_wasm --locked
• cargo tree -d --locked --all-features --target all no longer reports duplicate wasmparser

Not run: cargo deny check bans, because cargo-deny is not installed in this environment.
