   This PR follows our Release Process.

   It is required to open Transifex translations for v29.0, as scheduled in #31029.

   The previous similar PR: #30548.

   Notes for reviewers:

   1. This is the first release process conducted after migrating the build system to CMake. This revealed a bug, which is fixed in the second commit

   2. To reproduce the diff in the third commit, follow these steps:

   0gmake -C depends -j $(nproc) MULTIPROCESS=1
   1cmake --preset dev-mode --toolchain depends/$(./depends/config.guess)/toolchain.cmake
   2cmake --build build_dev_mode --target translate
   

2. Update Transifex slug for 29.x

   Update the Transifex slug to match the new resource created for the
   upcoming 29.x branch.

3. cmake: Ensure generated sources are up to date for `translate` target

   Some sources might be generated, and while they likely do not contain
   any translatable strings, this change generalizes the approach to
   include generated sources in the translation process as well.

4. qt: Update the `src/qt/locale/bitcoin_en.xlf` translation source file

   Steps to reproduce the diff:
   ```
   $ gmake -C depends -j $(nproc) MULTIPROCESS=1
   $ cmake --preset dev-mode --toolchain depends/$(./depends/config.guess)/toolchain.cmake
   $ cmake --build build_dev_mode --target translate
   ```

    I’m not sure how necessary 864386a7444fb5cf16613956ce8bf335f51b67d5 is (has this lead to an issue before?), but the rationale makes sense, and it seems harmless and a minimal change.

    I reviewed 2f27c910869e301b7e7669e81a0878da64e49957 without depends and with -DWITH_MULTIPROCESS=OFF because the sources lists of bitcoin-qt and bitcoin-gui are currently identical. Diff is the same.
