1. kernel: Unify .ctors and .init_array handling …

   Handle both of these sections in a single chunk of code instead of
   separately. We don't need to use the legacy .ctors ABI as both
   the constructors array and startup logic are managed within a single
   link result.
   
   This can now also be used with ARC MWDT which had been using the .ctors
   sections but with .init_array semantics. For ARC MWDT, we now always
   discard .dtors and .fini sections as Zephyr will never cause global
   destructors to execute. Stop discarding .eh_frame sections so that
   exception handling works as expected.
   
   When building a NATIVE_APPLICATION, we ask the native C library to run all
   of the constructors to ensure any non-Zephyr constructors are run before
   main is invoked. It might be "nice" to split the constructors so that the
   Zephyr constructors were executed by the Zephyr code while the non-Zephyr
   ones were executed by the native C library. I think that could be done if
   we knew the pathnames of either the Zephyr or non-Zephyr files. That might
   make a good future enhancement.

2. tests/kernel: Validate constructor execution order …

   Check the order of constructors, making sure those with a specified
   priority are called in numeric order after which those without priority are
   called.
