fbae8c59a2c3f102828a91ee0dbd6017daa1f4fb compat: Consolidate mingw-w64 ASLR workaround for upstream libsecp changes (fanquake)

Pull request description:

  #18702 added a work around for `bitcoin-cli.exe`, to fix ASLR on Windows. ASLR was functioning for the rest of our binaries, mostly by accident, because:
  > [All other Windows binaries that we distribute (bitcoind, bitcoin-qt,
  bitcoin-wallet, bitcoin-tx and test_bitcoin) do not suffer this issue,
  and currently having working ASLR. This is due to them exporting
  (inadvertent or not) libsecp256k1 symbols, and, as a result, the .reloc
  section is not stripped by ld.](https://github.com/bitcoin/bitcoin/pull/18702)

  Upstream, libsecp256k1 has recently made a change to [no-longer export symbols in static libraries](https://github.com/bitcoin-core/secp256k1/pull/1105) (see related discussion in #25008). This would mean that on the next subtree update, anyone building using an older binutils (< 2.36) would be (silently) producing Windows binaries with non-functioning ASLR. Our release binaries would not be affected, as in our Guix environment we currently use binutils 2.37.

  To prevent users building with older binutils from silently losing ASLR on Windows, this PR applies our work around (export `main`) to the rest of our binaries, and updates the associated documentation to mention the affected binutils versions, so we know when it can be dropped.

  I've included both the libsecp256k1 subtree update, and the ASLR related changes in this PR. Happy to split the changes up if reviewers would prefer.
