instrument: Use Import linkage for instrumentation functions (#5355)

These functions are getting far too complicated to code in SPIRV-Tools
C++. Replace them with import stubs so that the real implementations
can live in Vulkan-ValidationLayers where they belong.

VVL will need to define these functions in spirv and link them to the
instrumented version of the user's shader.

From here on out, VVL can redefine the functions and any data they use
without updating SPIRV-Tools. Changing the function declarations will
still require both VVL and SPIRV-Tools to be updated in lock step.
