Vang Thao 25d72330ff [AMDGPU] Add .uniform_work_group_size metadata to v5
Amdgpu kernel with function attribute "uniform-work-group-size"="true" requires
uniform work group size (i.e. each dimension of global size is a multiple of
corresponding dimension of work group size). hipExtModuleLaunchKernel allows to
launch HIP kernel with non-uniform workgroup size, which makes it necessary for
runtime to check and enforce uniform workgroup size if kernel requires it. To
let runtime be able to enforce that, this metadata is needed to indicate that
the kernel requires uniform workgroup size.
