Extend build system checks (#2039)

Browse Source 
* Adds check that ensures the Bazel and CMake Pico SDK version strings
  stay in sync.
* Adds check that ensures the Bazel pins for external dependencies stays
  in sync with the git submodule pins.
* Updates cyw43-driver pin in Bazel.
* Makes the checks for some build configurability options non-blocking.
