Merge bitcoin/bitcoin#31161: cmake: Set top-level target output locations

Browse Source 
568fcdddae scripted-diff: Adjust documentation per top-level target output location (Hennadii Stepanov)
026bb226e9 cmake: Set top-level target output locations (Hennadii Stepanov)

Pull request description:

  This PR sets the target output locations to the `bin` and `lib` subdirectories within the build tree, creating a directory structure that mirrors that of the installed targets.

  This approach is widely adopted by the large projects, such as [LLVM](e146c1867e/lldb/cmake/modules/LLDBStandalone.cmake (L128-L130)):
  ```cmake
  set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
  set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
  set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
  ```

  The `libsecp256k1` project has also recently [adopted](https://github.com/bitcoin-core/secp256k1/pull/1553) this approach.

  With this PR, all binaries are conveniently located. For example, run:
  ```
  $ ./build/bin/fuzz
  ```
  instead of:
  ```
  $ ./build/src/test/fuzz/fuzz
  ```

  On Windows, all required DLLs are now located in the same directory as the executables, allowing to run `bitcoin-chainstate.exe` (which loads `bitcoinkernel.dll`) without the need to copy DLLs or modify the `PATH` variable.

  The idea was briefly discussed among the build team during the recent CoreDev meeting.

  ---

  **Warning**: This PR changes build locations of newly built executables like `bitcoind` and `test_bitcoin` from `src/` to `bin/` without deleting previously built executables. A clean build is recommended to avoid accidentally running old binaries.

    Light re-ACK 568fcdddae
  ryanofsky:
    Code review ACK 568fcdddae. Only change since last review was rebasing. I'm ok with this PR in its current form if other developers are happy with it. I just personally think it is inappropriate to \*silently\* break an everyday developer workflow like `git pull; make bitcoind`. I wouldn't have a problem with this PR if it triggered an explicit error, or if the problem was limited to less common workflows like changing cmake options in an existing build.
