Extends the wheel test continuous and nightly release workflows to run against TheRock 7.13.0 and TheRock latest builds in addition to ROCm 7.2.0.
Consolidate the ROCm wheel RUNPATH strategy in jaxlib/rocm/rocm_rpath.bzl and embed it at link time via _WHEEL_RPATHS instead of a post-build patchelf step (applied under rocm_path_type=link_only, which the release wheel config sets). A single wheel resolves ROCm libs across TheRock pip wheels (1- and 2-deep $ORIGIN layouts), TheRock tarballs under /opt/rocm-<ver>, and legacy /opt/rocm; the loader silently skips $ORIGIN entries whose directories don't exist. Also pin the hermetic build ROCm to the image's TheRock version via ROCM_DISTRO_URL so the wheel's ROCm SONAMEs match the runtime image.

On the single-GPU ROCm runner, all xdist workers map to GPU 0 and share the same MIOpen user DB lock. This causes MIOpen kernel lookups to serialize across workers, reducing effective parallelism and increasing CI runtime. Configure a dedicated
MIOPEN_USER_DB_PATHandMIOPEN_CUSTOM_CACHE_DIRfor each xdist worker so MIOpen cache locks are not shared between workers.
