Merge #17740: build: remove configure checks for win libraries we don't link against

2525c096b002a89d4c561e1474800496ad8ebd7e build: remove configure checks for win libraries we don't link against (fanquake)

Pull request description:

  While cross compiling, `HOST=x86_64-w64-mingw32`, none of these libs actually seem to be passed to the linker. i.e tailing a build with `make -j5 V=1 | rg -i 'mingwthrd|winspool|rpcrt4|crypt32'`.

  I'm not 100% sure about `crypt32`, even though the majority of our Windows cryptography usage, i.e [`CryptAcquireContextW`](https://docs.microsoft.com/en-us/windows/win32/api/wincrypt/nf-wincrypt-cryptacquirecontextw) or [`CryptGenRandom`](https://docs.microsoft.com/en-us/windows/win32/api/wincrypt/nf-wincrypt-cryptgenrandom) is provided by `advapi32`.

  Note that `rpcrt4` and `mingwthrd` are already missing from the MSVC build, so we can sync the remainder once it's clear what's actually needed. Hopefully sipsorcery can add some MSVC insight.
