[PATCH v2 0/4] MR4378: Extend CreateProcess tests for handle inheritance.

[eric pouech (＠epo)]

This serie adds a couple of test for CreateProcess around
std handles inheritance, depending on several options (cui/gui,
use (or no use) of STARTF_USESTDHANDLES, type of handles...).

This requires revisiting the existing tests to allow for more
flexibility in implementing the new tests (and potentially
others if needed).

--
  v2: kernel32/tests: Add tests for std handles inheritance in CreateProcess.
      kernel32/tests: Revisit argument generation in CreateProcess tests.
      kernel32/tests: Detect null/invalid handles, return file type as well.
      kernel32/tests: Extend returned values for cui/gui tests.
