Merge bitcoin/bitcoin#29706: depends: set two CMake options globally 
76045bb9d6808931cd0f2933203b5b611e032ec8 depends: always set CMAKE_POSITION_INDEPENDENT_CODE=ON (fanquake)
d04623678c70ff58a20fb5c35d33cb8f483f1efb 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 #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).

ACKs for top commit:
  hebasto:
    re-ACK 76045bb9d6808931cd0f2933203b5b611e032ec8.
  theuni:
    utACK 76045bb9d6808931cd0f2933203b5b611e032ec8. Both changes make sense to me, and both can be overridden if needed, though I can't imagine we'd need to.
