MSL: Implement CompositeInsert OpSpecConstantOp.
This op creates a new composite constant with one element replaced. So, we reconstruct the `SPIRConstant` for the composite constant, but with one of the IDs replaced. Constant initializer lists are memoized for when the result of a `CompositeInsert` is used in another `CompositeInsert`. (I wanted to add a test case for GLSL as well, but for two things: 1. `glslang` in Vulkan mode chokes on the first constant array, insisting that its initializer needs to be a constant. [Bug in glslang?] 2. The declarations for the buffers used by the shader aren't emitted, regardless of whether Vulkan mode is enabled.) Fixes five tests under `dEQP-VK.spirv_assembly.instruction.*.opspecconstantop.vector_related`.
