It's usable in VLC 3.0 since 9ae9d8279bd0b82ae7abe70ed304a526db952488

We can use the winstorecompat wincrypt.
We don't need stdatomics fixes as we don't use MSVC

This image has:
- a newer clang
- newer mingw-w64 headers/libs that are cleaner regarding UWP support
- compiled runtimes compiled with ucrt (as the image it's replacing)

Patches to build gnutls properly from an official build are merged upstream.

- gcrypt is cleaned in master
- libarchive is cleaner in master

- remove patches merged in 3.0 master

Using the same as in build.sh now.

- remove cmake/meson patches that are merged in master
- rebase other patches on master

- don't build mfx for arm*

- update mfx so it can build properly for UWP targets

- update mpg123 to the latest version and cleaner patches

- update cmake so it works better with clang+mingw+uwp
- update meson so it works better with clang+mingw
- fix libarchive fixes

The current mingw toolchain doesn't allow GetFileSizeEx in winstore builds.

Update harfbuzz and fix the direct WINAPI_FAMILY_PC_APP/WINAPI_FAMILY_PHONE_APP
usage. It doesn't exist in mingw.

The libarchive patches need some updating after updating to 3.4.0.

The patches can be found in https://code.videolan.org/robUx4/vlc-3.0/-/tree/winstore/5

The patches can be found in https://code.videolan.org/robUx4/vlc/-/tree/winstore/4

And cmake and libtool when building with LLVM

It's easier to debug that way

It's a now variable that Make will use.

As found in WSL.
