[Spec Constants] Improved handling of invalid/unsupported spec. const…

…ants

Two main changes to how `Kernel/ProgramSetSpecializationConstants`
are handled:
* They may now output either `INVALID_VALUE` or the new
  `INVALID_SPEC_ID` when the provided list is invalid.
* The OpenCL and level 0 adapters now respond to
  `UR_DEVICE_INFO_KERNEL_SET_SPECIALIZATION_CONSTANTS` with `false`
  rather than erroring out. This fixes some tests that were
  incorrectly not being skipped.
* `urKernelSetSpecializationConstants` now "implemented" (as a
  function that returns `UNSUPPORTED_FEATURE` for a number of
  adapters.
