It generates compilation errors before as it's not supported.

rebased:
- 3.0 has winstore compat above

Just like we favor the static version of libunwind.

We don't need any extra flags for the compiler. It's all handled in the linker.

Ref. #28903

edited:
- 3.0 had more/in different places

This way it's enabled the same way for all the code we build.

(cherry picked from commit 2c2eb681)

This may trigger some compiler detection in some contribs.
The warning is issued when linking through the compiler.

(cherry picked from commit 112d5c78)

Only used in UWP builds.

edited:
- 3.0 has winstorecompat library

Only ignore the options we add locally.
This is how it's done in the llvm-mingw wrappers.

Otherwise it may use the dynamic libunwind (as found in meson).

Don't emit errors if it's not using (when only compiling). Some contribs don't like that.

edited:
- 3.0 doesn't have meson support

We did the detection, we know what we should use.

(cherry picked from commit 55d61600)

So it applies to autotools and meson builds.
It's currently forced in the configure script.

(cherry picked from commit 4290a69d)

So we know the tools that need to be built from there.

(cherry picked from commit 41bbcde5)

The mingw-w64 LLVM packages use XXX-w64-mingw32uwp for UWP targets.

This will enable HAVE_WINSTORE in contribs.

The documentation says it's either 1 or 2.
I verified this is the case in FFmpeg 7.1. Only h264dec, mpeg12dec, mpegvideo_parser, vc1 set it.
