[mlir][GPU] Link relevant LLVM components in GPUCommon instead of test

[ftynse]

Summary

D80142 restructured MLIR-to-GPU-binary conversion to support multiple
targets. It also modified cmake files to link relevant LLVM components
in test/lib, which broke shared-library builds, and likely made the
conversions unusable outside mlir-opt (or other tools that link in test
library targets). Link these components to GPUCommon instead.

@ftynse Thanks for the patch. Wondering would it be a better idea to amend the text at: https://mlir.llvm.org/getting_started/ so -DBUILD_SHARED_LIBS=ON is always turned on?
