[AMDGPU] Add dynamic stack bit info to kernel-resource-usage Rpass output

In code object 5 (https://llvm.org/docs/AMDGPUUsage.html#code-object-v5-metadata) the AMDGPU backend added the .uses_dynamic_stack bit to the kernel meta data to identity kernels which have compile time indeterminable stack usage (indirect function calls and recursion mainly). This patch adds this information to the output of the kernel-resource-usage remarks.
