test(arkts): add byte_offset to Expr::Call inits — fix harmonyos-smoke compile after #5250 (#5288)

#5250 added `Expr::Call.byte_offset` but missed the `Expr::Call { .. }`
initializers in perry-codegen-arkts's tests (3 in src/tests.rs, 3 in
tests/phase2_full_app_smoke.rs). perry-codegen-arkts isn't built by the gating
`cargo-test` job, only by the informational `harmonyos-smoke` job
(continue-on-error), so this E0063 sat red on main — and on every open PR —
without blocking anything. Mirrors the #5266 cheerio fix.

After: `cargo test -p perry-codegen-arkts --lib` (111 passed) and
`--test phase2_full_app_smoke` (2 passed) both green. No version/CHANGELOG/Cargo.lock edits.
