Subject: [PATCH 1/2] Use ParallelTestRunner.jl to parallelize the tests

Follows MathOptInterface (jump-dev/MathOptInterface#2932): test files are
renamed to `test_*.jl` and discovered by `test/runtests.jl`, which hands
them to `ParallelTestRunner.runtests`. Helper files (`Transformer.jl`,
`OptimisersSolver.jl`) keep their names so they are not picked up as
testsets, and the Julia v1.10 exclusions are kept.
