Pull request description:

  In Bitcoin Core v22.0, we [switched](https://github.com/bitcoin/bitcoin/pull/21694) from Qt TS to XLIFF translation source file to provide more context, specifically [developer notes](https://doc.qt.io/qt-6/i18n-source-translation.html#add-comments-for-translators), to translators on Transifex. That was very useful for translators back then, even though it required some extra complexity on our side.

  Since then, Transifex has enabled support for developer notes in [Qt TS files](https://help.transifex.com/en/articles/6223301-qt-linguist) as well.

  Therefore, I believe we should thank XLIFF for its service and retire it.

  In addition to switching back to Qt TS, this PR introduces a few tweaks to the  `lupdate` command (see the corresponding commit messages).

  To summarize, this PR brings the following benefits:
  1. Removal of obsolete code from the build system.

  2. Minimal diffs during translation updates. For a recent example, see https://github.com/bitcoin-core/gui/pull/931. One can also apply the changes from bitcoin/bitcoin#34301 and run `cmake -B build --fresh -DBUILD_GUI=ON && cmake --build build -t translate` to observe the new minimal diff.

  3. More stable string hashes on Transifex. They no longer include string `id`s, which makes this PR an alternative to https://github.com/bitcoin/bitcoin/pull/33270.

  As a potential drawback, we are tying ourselves back to Qt's proprietary translation file format.

  I've created an experimental resource on Transifex based on this branch: https://app.transifex.com/bitcoin/bitcoin/experimental-do-not-translate. Reviewers can use it to observe Transifex's support for the various features on the following messages:
  - \# 11 - Developer Notes
  - \# 144 - Plurals
  - \# 510 - A disambiguation string (provided as a second argument to the [`tr()`](https://doc.qt.io/qt-6/qobject.html#tr) function) added to the string context.

Bitcoin Core

Setup

Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.

To download Bitcoin Core, visit bitcoincore.org.

Running

The following are some helpful notes on how to run Bitcoin Core on your native platform.

Unix

Unpack the files into a directory and run:

  • bin/bitcoin-qt (GUI) or
  • bin/bitcoind (headless)
  • bin/bitcoin (wrapper command)

The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.

Windows

Unpack the files into a directory, and then run bitcoin-qt.exe.

macOS

Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
