Rollup merge of #90782 - ricobbe:binutils-dlltool, r=michaelwoerister

Implement raw-dylib support for windows-gnu

Add support for `#[link(kind = "raw-dylib")]` on windows-gnu targets.  Work around binutils's linker's inability to read import libraries produced by LLVM by calling out to the binutils `dlltool` utility to create an import library from a temporary .DEF file; this approach is effectively a slightly refined version of `@mati865's` earlier attempt at this strategy in PR #88801.  (In particular, this attempt at this strategy adds support for `#[link_ordinal(...)]` as well.)

In support of #58713.
