Martin Storsjö 866d47cced wrappers: Pick up the Clang config file implicitly 
Clang only picks up config files implicitly using the normalized
triple form, so use file names with "-windows-gnu" instead of
"-mingw32".

In theory, we could also want to pick up the config file implicitly
by having "<triple>-<mode>" be a symlink directly to the clang
executable. That works for regular mingw32 targets, but for the
mingw32uwp target, there's no distinction in the normalized
triple, so both would end up using the same "-windows-gnu" config
files. So as long as we want to support the mingw32uwp prefixed
tools, we need to use a wrapper.

Martin Storsjö e0964ce24c Revert use of Clang config files 
This reverts commit 49db4a3a15,

When relying on Clang config files, two issues appeared:

- Running the compiler-rt tests fails, because the compiler-rt tests
  disable any default config files, breaking the compiler
  in this case:
  https://github.com/llvm/llvm-project/blob/llvmorg-19.1.1/compiler-rt/test/lit.common.cfg.py#L983

- Wine fails to build using llvm-mingw as cross compiler, because
  Wine adds the --no-default-config flag to Clang while compiling,
  if supported:
  https://gitlab.winehq.org/wine/wine/-/blob/wine-9.19/configure.ac?ref_type=tags#L866-868
  This causes llvm-mingw to omit the -rtlib=compiler-rt option
  (specified in a config file), making the compiler look for libgcc
  instead. Doing a check to see that linking succeeds doesn't necessarily
  help here - such a check already exists, but it tests linking with
  -nostdlib -nodefaultlibs:
  https://gitlab.winehq.org/wine/wine/-/blob/wine-9.19/aclocal.m4?ref_type=tags#L193-L206
