ENH: Add builds for ITK-5.4.2

[hjmjohnson]

Add macos-15 build and ITK5.4.2 tags.

[dzenanz]

We should test this in at least one remote module. Maybe we should keep a branch named v5.4.2, to keep the same pattern with v5.4.0.

[dzenanz]

I now see that 5.4.2 wheels are not up yet. Maybe we should revert this until then?

[hjmjohnson]

@dzenanz I don't know how to make the wheels. I won't be able to work on this for a while. revert if you want.

[dzenanz]

Here are the instructions for wheel generation:

[dzenanz]

That task is tracked here: InsightSoftwareConsortium/ITK#5144. Matt, do you plan to do that?

[dzenanz]

I tested this in Montage module, and I realized that for C++ testing, it does not matter that Python wheels do not exist. So there is no urgent need to revert this. Some problems are possible due to ITK version discrepancy between C++ (5.4.2) and Python (5.4.0).

Yes, I plan to start Python package builds for 5.4.2 this week.

But Python packages are not needed for this change.

However, adding macos-15 for the C++ builds makes C++ macos-14 unnecessary.

[dzenanz]

C++ macos-14 unnecessary

Removing code is easier than adding.

I noticed that the new build type has a very long name (build-test-cxx (macos-15, clang, clang++, MinSizeRel)), as seen here. The other builds have shorter names, e.g. build-test-cxx (macos-14).
