Add rocm_test_stats HUD page (#8234)

Add a new **ROCm Test Stats** HUD page under Dev Infra
(`/rocm_test_stats`), mirroring the existing `/cuda_test_stats` and
`/mac_test_stats` pages added in #8127.

This is a wrapper around the shared `TestStatsPage` component and reuses
the existing `test_stats_per_commit` ClickHouse query (no query or
shared-component changes). It shows per-commit total/skip/flaky/fail
counts for `pytorch/pytorch` trunk ROCm jobs.

- Restricted to the `trunk` workflow (runs on every push to `main`) and
jobs matching `(?i)jammy.*rocm|rocm.*jammy` — i.e. the
`linux-jammy-rocm-py3.10-mi355` build/test jobs defined in `trunk.yml`.
- Adds a NavBar entry `ROCm test stats`.

## Test plan
- Navigate to `/rocm_test_stats` and confirm per-commit ROCm counts
render, with `?count=N` and `?sha=<hex>` working.
