spirv: Add support for DerivativeGroup capabilities

As defined in SPV_NV_compute_shader_derivatives. These control how the
invocations are arranged in a CS when doing derivative and related
operations (which are also enabled by the extension).

Since we expect valid SPIR-V, we don't need to do more work at SPIR-V
level to enable the derivative and related operations to be called.
