Subject: [PATCH] ci: use centralized tests.yml@v1 (with num-threads: 2)

Convert the bespoke Tests.yml to a tests.yml@v1 caller now that the
reusable workflow supports `num-threads` (SciML/.github#43). Preserves the
exact version x group matrix and JULIA_NUM_THREADS=2 (needed so the
threaded regression tests for #570 actually exercise the multi-thread path)
and coverage-directories src,ext.
