The KernelEnvironment is for compile time information about a kernel. It allows the compiler to feed information to the runtime. The KernelLaunchEnvironment is for dynamic information *per* kernel launch. It allows the rutime to feed information to the kernel that is not shared with other invocations of the kernel. The first use case is to replace the globals that synchronize teams reductions with per-launch versions. This allows concurrent teams reductions. More uses cases will follow, e.g., per launch memory pools. Fixes: https://github.com/llvm/llvm-project/issues/70249
