shared_module creates import library on MinGW

[kmilos]

Describe the bug When building Python packages using MinGW, import libraries (.dll.a) are created in addition to the .pyd extensions.

See e.g. https://github.com/msys2/MINGW-packages/pull/18706#issuecomment-1747098489

Expected behavior shared_module() should not produce .dll.a import library artifact on MinGW like a shared_library() does, only the shared object itself

system parameters

• Is this a cross build or just a plain native build (for the same computer)? - native
• what operating system - MSYS2 UCRT64 on Windows 10
• what Python version are you using - 3.11.6
• what meson --version - 1.2.2
• what ninja --version - 1.11.1

This doesn't seem to be exclusive to Python modules, it looks like shared_module does this in general.
