Update JET tests that now pass with improved type stability

Several JET tests that were previously marked as broken now pass due to
the type stability improvements in LinearVerbosity:

- QRFactorization
- LDLtFactorization
- BunchKaufmanFactorization
- FastLUFactorization
- FastQRFactorization
- KrylovJL_GMRES
- KrylovJL_MINRES
- KrylovJL_MINARES

Changed from @test_opt broken=true to @test_opt for these passing tests.
