Disable/allow some clang-tidy and clang warnings

* Disable bugprone-unchecked-optional-access because it
  crashed with some Android files.
* Allow misc-const-correctness and bugprone-assignment-in-if-condition
  as warnings, not to stop build as errors.
  Disable them in the global default check list.
* Allow/show clang deprecated* and array-parameter warnings for the NEXT version.
