CI: All-Static builds (Linux/macOS/Win)

[ax3l]

Downstream, it makes sense for some deployments (e.g., PyPA/pip of openPMD-api) to build an all-static ADIOS2 builds with all-static dependencies.

This often breaks in ADIOS2 #4019 #3898 #3716 #2747 #2454 #2316 #2576 #1810 ...

Could we add a CI entry for each Linux/macOS/Win that:

• builds all ADIOS2 dependencies as static
• builds ADIOS2 as static
• does smoke tests?

Currently, we only have three static Linux builds in CI. I am not sure they also test dependencies like C-Blosc2 (static!).

For our use case, covering serial is sufficient.

Note: we definitely want to keep shared builds for the same combinations too (esp. Windows DLL exports are tricky and need coverage).

The windows static builds will require work on the thirdparty GTkorvo libraries. I've started that.

I believe that his has been fixed in #4037 and #4041
