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

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.

  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.

The first time you run `bitcoind` or `bitcoin-qt`, it will start downloading the blockchain.
