[PATCH v1 2/2] perftest: extend ROCm CI to compile device code per target arch

[Stephen Bates <sbates@raithlin.com>]

The ROCm CI job added previously builds everything but passes no
--with-rocm-arch flag, so the hip kernel is compiled for the host
only. Now that --with-rocm-arch exists and the 7.2.4 slim image ships
device support for gfx950 and gfx1250, fan the job into one leg per
architecture.

fail-fast: false keeps both legs running so a device-specific failure
in one does not hide the other leg's result.
