[sksl] Support all compute stage inputs

Added support for all compute stage builtin input variables using
the GLSL style sk_NumWorkgroups, sk_WorkgroupID, sk_LocalInvocationID
sk_GlobalInvocationID, sk_LocalInvocationIndex.

These variables very closely match the corresponding variable names in
OpenGL, Vulkan, and WebGPU. They also very specifically capture each
variable's meaning and domain compared to the existing
sk_ThreadPosition.
