  • Extended Fuzzlyn CI configuration to include dedicated async runtime testing partitions
  • Modified command construction to conditionally include async generation extensions

PTAL @dotnet/jit-contrib

Some somewhat simple changes (with some corresponding changes in the Fuzzlyn repo). Adds 4 additional partitions that run weekly runtime async testing. Will probably tune down to 4 or 6 total partitions once rc2/GA snaps.
