build(win): make the mingw cross-compile link and find librustzcash

Three things broke the x86_64-w64-mingw32 build; two are real and fixed
here (the third was a stale-object contamination from building Linux and
Windows in the same tree, resolved by a clean rebuild — not a code fix).

1. Single-pass mingw ld could not resolve the cross-references DragonX
   added between the internal static archives (libbitcoin_util/common
   objects pulling in UniValue; util<->common mutual deps). GNU ld on
   Linux re-scans archives so it never surfaced; ld64 on macOS rejects
   the grouping flag outright. Bracket each binary's _LDADD in
   -Wl,--start-group/--end-group, delivered via AC_SUBST(LINK_GROUP_*)
   so automake does not reject the linker flag inside _LDADD, and left
   empty on every non-Windows target.

2. The Rust build emits the mingw archive as rustzcash.lib, but the
   link line asks for -lrustzcash, i.e. librustzcash.a. Normalize the
   staged filename to librustzcash.a for every host (a no-op on
   Linux/macOS, where the basename was already librustzcash.a).
