ENH: Convert four no-arg Common tests to GoogleTest

[hjmjohnson]

Mechanical CTest → GoogleTest conversion of four no-argument tests in Modules/Core/Common/test/. All four pass locally against ITKCommonGTestDriver.

Commit summary

#	Test	Pattern
1	itkImageAdaptorPipeLineTest → itkImageAdaptorPipeLineGTest	Single commit (rename + edit, 96% similarity)
2	itkExtractImage3Dto2DTest → itkExtractImage3Dto2DGTest	Single commit (rename + edit, 83% similarity)
3	itkExtractImageTest → itkExtractImageGTest	Two commits — pure rename then body edit (preserves git log --follow)
4	itkMinimumMaximumImageCalculatorTest → itkMinimumMaximumImageCalculatorGTest	Two commits — pure rename then body edit

Mechanical-conversion details

• int itkFooTest(int, char *[]) → TEST(Foo, ConvertedLegacyTest).
• if (...) return EXIT_FAILURE; → EXPECT_* (or FAIL() << "msg" when the original printed a terminal error message).
• ITK_TEST_SET_GET_VALUE → EXPECT_EQ (the macro's expansion includes return EXIT_FAILURE, incompatible with TEST() void bodies).
• ITK_TEST_EXPECT_TRUE → EXPECT_TRUE (same reason).
• return ExtractImageInPlaceTest() → call as void; helper signature changed from bool to void (it only contained EXPECT_TRUE checks).
• Comments preserved verbatim. std::cout diagnostic prints kept.
• New *GTest.cxx files added to ITKCommonGTests set (alphabetical position); legacy entries removed from ITKCommon{1,2}Tests and the corresponding itk_add_test(...) blocks deleted.

Fixed Windows MSVC compile error in a5e6834 (squashed via git rebase --autosquash).

ITK_EXERCISE_BASIC_OBJECT_METHODS expands differently on MSVC vs GCC: the MSVC variant contains return EXIT_FAILURE; on class-name mismatch, which is illegal inside a TEST() body (void). Replaced the macro call with explicit Print() + two EXPECT_STREQ checks, and removed the now-orphaned #include "itkTestingMacros.h".

Verified locally: ITKCommonGTestDriver --gtest_filter='MinimumMaximumImageCalculator.*' passes.

I think there is exercise_basic_object_gtest (or similarly named) macro.

exercise_basic_object_gtest

I think there is exercise_basic_object_gtest (or similarly named) macro.

Yes. and I noted it for future conversions, so hopefully this does not show up again.

ITK_GTEST_EXERCISE_BASIC_OBJECT_METHODS(calculator, MinimumMaximumImageCalculator, Object);
