test: raise the contended Windows spawn budgets to 90s

The per-case 15-30s budgets on the Windows native and coverage lanes fire
before oxlint, workflow-worker-thread, and other subprocess-spawning cases
finish under the loaded self-hosted pool; the failures rotate across cases
as load shifts, so per-case widening only moved the flake. Raise the lane
defaults (DSH_COVERAGE_TEST_TIMEOUT_MS and the native --testTimeout) to 90s,
align the oxlint and workflow-worker-thread case budgets, and keep the
built-bin SPAWN_TIMEOUT_MS at 60s under a 90s outer budget.
