11d797e depends: Build `native_capnp` package with CMake (Hennadii Stepanov)
90389c9 depends: Build `capnp` package with CMake (Hennadii Stepanov)

Pull request description:

  The first commit fixes two bugs when cross-compiling the `capnp` package on the master branch @ 160d236:
  - for `x86_64-w64-mingw32` (see bitcoin/bitcoin#28735 (comment)):
  ```

  ```
  - for `arm64-apple-darwin`:
  ```
  checking build system type... x86_64-pc-linux-gnu
  checking host system type... Invalid configuration `arm64-apple-darwin': machine `arm64-apple' not recognized
  configure: error: /bin/bash build-aux/config.sub arm64-apple-darwin failed
  ```

  The second commit applies the same changes for the `native_capnp` package for [consistency](bitcoin/bitcoin#28856 (comment)).

ACKs for top commit:
  ryanofsky:
    Code review ACK 11d797e. Since last review arm64-apple-darwin platform is now mentioned in the commit message, and the change to `depends/packages/libmultiprocess.mk` in d1604d4b1d1ee8df279a1776303e167cc3d06193 which was unrelated (but probably still a good optimization) was reverted.
