ENH: handle wmake -debug option via FOAM_EXTRA_CXX_FLAGS

- ensures that subsequent Allwmake scripts know about it.

ENH: add bin/tools/query-detect wrapper for wmake have_* scripts

CONFIG: use project/ThirdParty without additional sanity checks

- no need to test for Allwmake or platforms/ if ThirdParty is located
  within the project directory itself.

COMP: add simple mpi test to 00-dummy

- for testing library linkage, etc.

 Class
-    Foam::Detail::dummyLib
+    Foam::Detail::dummy
 
 Description
-    This class serves little useful purpose, but can be used to compile
-    into a dummy library and link against for a minimal application
-    that uses the wmake framework
+    No useful purpose other than to use the wmake framework to generate
+    a dummy library for testing/packaging purposes
+
+Note
+    Pure C++ without any OpenFOAM classes or libraries.
