Previously, `kDeviceThreadAxis` defined the IterVar to be used for each thread/block axis, and `kUseDynamicSharedMemoryTag` defined whether dynamic memory allocations exist, which are primarily used to produce a list of strings by `tvm::codegen::ExtractFuncInfo`. Because `kDeviceThreadAxis` is a `Array<IterVar>`, the IterVar is used prior to its definition site at `tir::attr::thread_extent`, which results in errors when attempting to round-trip through TVMScript. This commit replaces these attributes with `attr::kKernelLaunchParams`, which directly contains the kernel launch parameters. These are expressed as an `Array<String>`, allowing the generated TVMScript to successfully round-trip.
