mingw: delete support for legacy mingw.org toolchain
Drop support for "old" / "legacy" / "classic" / "v1" / "mingw32" MinGW:
  https://en.wikipedia.org/wiki/MinGW, https://osdn.net/projects/mingw/
Its homepage used to be http://mingw.org/ [no HTTPS], and broken now.
It supported the x86 CPU only and used a old Windows API header and
implib set, often causing issues. It also misses most modern Windows
features, offering old versions of both binutils and gcc (no llvm/clang
support). It was last updated 2 years ago.

curl now relies on toolchains based on the mingw-w64 project:
https://www.mingw-w64.org/  https://sourceforge.net/projects/mingw-w64/
https://www.msys2.org/  https://github.com/msys2/msys2
https://github.com/mstorsjo/llvm-mingw
(Also available via Linux and macOS package managers.)

Closes #11625

Items to be removed from future curl releases

If any of these deprecated features is a cause for concern for you, please email the curl-library mailing list as soon as possible and explain to us why this is a problem for you and how your use case cannot be satisfied properly using a workaround.

space-separated NOPROXY patterns

When specifying patterns/domain names for curl that should not go through a proxy, the curl tool features the --noproxy command line option and the library supports the NO_PROXY environment variable and the CURLOPT_NOPROXY libcurl option.

They all set the same list of patterns. This list is documented to be a set of comma-separated names, but can also be provided separated with just space. The ability to just use spaces for this has never been documented but some users may still have come to rely on this.

Several other tools and utilities also parse the NO_PROXY environment variable but do not consider a space to be a valid separator. Using spaces for separator is probably less portable and might cause more friction than commas do. Users should use commas for this for greater portability.

curl will remove the support for space-separated names in July 2024.
