7703884 Fix MSVC warning C4273 "inconsistent dll linkage" (Hennadii Stepanov)

Pull request description:

  Broken out of bitcoin#30454.

  When using CMake, the user can select the MSVC runtime library to be:
  1) Statically-linked (with the corresponding `x64-windows-static` vcpkg triplet) or
  2) Dynamically-linked (with the corresponding `x64-windows` vcpkg triplet)

  In the latter case, the compiler emits the [C4273](https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-1-c4273) warning.

  As the "Necessary on some platforms" comment does not apply to MSVC, skip the declaration for MSVC.

  The MSVC build system in the master branch supports the statically-linked runtime only: https://github.com/bitcoin/bitcoin/blob/ed739d14b58b5e772a65b85bb421703963b06852/build_msvc/common.init.vcxproj.in#L65

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#28735 (comment)):

  ```

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

    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 d1604d4 which was unrelated (but probably still a good optimization) was reverted.

bde8d63 depends: build libmultiprocess with position independant code (fanquake)
506634d depends: always install libmultiprocess to /lib (fanquake)
beb3096 depends: always install capnp to /lib (fanquake)

Pull request description:

  Change to always install libmultiprocess into `lib/`. On some systems (my Fedora aarch64 box), libmultiprocess was being installed into `lib64/`, and then configure would fail to pick it up, because we only add `lib/` to pkgconfig/ldflags out of depends. Rather than adding lib64 to those, I opted for installing libmultiprocess into lib, with every other dependency we build.

  This was broken in our build after bitcoin-core/libmultiprocess#79 upstream.

    Code review ACK bde8d63. Only changes since last review were reverting the native_capnp change as suggested, and changing the order of the first two commits.

76045bb depends: always set CMAKE_POSITION_INDEPENDENT_CODE=ON (fanquake)
d046236 depends: always set CMAKE_INSTALL_LIBDIR=lib/ (fanquake)

Pull request description:

  Set `CMAKE_INSTALL_LIBDIR=lib/` and `CMAKE_POSITION_INDEPENDENT_CODE=ON` globally in depends, rather than per-package. `CMAKE_INSTALL_LIBDIR=lib/` is needed to override the annoying [`GNUInstallDirs`](https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html) `lib` vs `lib64` behaviour, and we always want PIC code. The PIC commit is the counterpart to the same Autotools change in bitcoin#29488. I'm PRing these commits as I have a CMake branch building on top, and want to avoid adding the same workarounds to every package we are going to touch, but these can go in separately as the build should be tested for existing packages (i.e multiprocess).

eff19fa build, macos: Drop unused `osx_volname` target (Hennadii Stepanov)

Pull request description:

  The `osx_volname` makefile target was introduced in bitcoin#7192 and was used to pass the package name to Gitian scripts as a content of the `osx_volname` file.

  With the current Guix scripts, the `osx_volname` file is never read. Therefore, its creation might be omitted.
