Pull request description:
This moves packages in depends that use `.tar.bzip2` to `.tar.gz` (which is what we use for our own release tarballs). Doing so means we can drop `bzip2` from our Guix release env. You can observe that Guix building master without it would currently fail:

0244416aac security: restrict abis in bitcoind.service (Charlie)
Pull request description:
[As noted here](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#MemoryDenyWriteExecute=), it's a good idea to pair `MemoryDenyWriteExecute=true` with `SystemCallArchitectures=native` because `MemoryDenyWriteExecute` can be circumvented in some operating systems which support multiple ABIs like x86/x86-64.
This helps restrict the possible application binary interfaces (ABIs) that can be used when running bitcoind through systemd, reducing the attack surface area.

007ea322a6 depends: switch to building libqrencode with CMake (fanquake)
884330c0a5 guix: make cmake-minimal a global requirement (fanquake)
Pull request description:
Switch to building libqrencode with CMake. Note that upstream (https://github.com/fukuchi/libqrencode) hasn't seen any activity for ~4 years, so the odds of getting anything upstream seems low, but I've made two minor changes to the source here, which I will PR in any case.
From an initial look I couldn't find any significant difference between the Autotools and CMake produced libs. As part of this change we move cmake-minimal in Guix into the global package set.

73d92309d7 guix: use GCC 11 for macOS builds (fanquake)
Pull request description:
Note that this is just the native compiler, which is used to build the toolchain we use to build the actual binaries.
Partially motivated by #29091, where it could now be a bit confusing if we are explicitly using GCC 10 in our release toolchain, when our minimum required is 11 (this can't be bumped to 12 due to build issues with native tools).
At the same time, remove `gcc-toolchain "static"` from the macOS build env.

Pull request description:
The `osx_volname` makefile target was introduced in https://github.com/bitcoin/bitcoin/pull/7192 and was used to pass the package name to Gitian scripts as a content of the `osx_volname` file.
With the current Guix scripts, the `osx_volname` file is never read. Therefore, its creation might be omitted.

7850c5fe20 guix: build GCC with --enable-standard-branch-protection (fanquake)
Pull request description:
This is one change extracted from #24123 (which now produces fully BTI & PAC enabled bins), which will mean that everything in depends, for Guix builds, is compiled using `-mbranch-protection=standard`.
Turning this on by default, is similar to what we already do with `--enable-default-ssp`, `--enable-default-pie` etc.
See: https://gcc.gnu.org/install/specific.html#aarch64-x-x
> To enable Branch Target Identification Mechanism and Return Address Signing by default at configure time use the `--enable-standard-branch-protection` option.
> This is equivalent to having `-mbranch-protection=standard` during compilation. This can be explicitly disabled during compilation by passing the `-mbranch-protection=none` option which turns off all types of branch protections.

Retain native GCC 10 toolchain for macOS, to prevent compile failures in
native tools (this will be removed entirely when we tansition to LLD).
Update the vmov-alignment patch, for changes in GCC 12.

Pull request description:
By defining a virtual interface class for the scheduler client, users of the kernel can now define their own event consuming infrastructure, without having to spawn threads or rely on the scheduler design.
Removing `CScheduler` also allows removing the thread and exception modules from the kernel library.
To make the `CMainSignals` class easier to use from a kernel library perspective, remove its global instantiation and adopt RAII practices.
Renames `CMainSignals` to `ValidationSignals`, which more accurately describes its purpose and scope.
Also make the `ValidationSignals` in the `ChainstateManager` and CTxMemPool` optional. This could be useful in the future for using or testing these classes without having to instantiate any form of signal handling.

This PR is part of the [libbitcoinkernel project](https://github.com/bitcoin/bitcoin/issues/27587). It improves the kernel API and removes two modules from the kernel library.

faa30a4c56 rpc: Do not wait for headers inside loadtxoutset (MarcoFalke)
Pull request description:
While the `loadtxoutset` default 10 minute timeout is convenient when it is sufficient, it may cause hassle where it is not. For example:
* When P2P connections are missing, it seems better to abort early than wait for the timeout.
* When the 10 minute timeout is not sufficient, the RPC will have to be called again, so a check or loop is needed outside the RPC either way. So might as well remove the loop inside the RPC.

This is done in preparation for the next two commits, where the
CMainSignals are de-globalized.
This avoids adding new constructor arguments to the ChainstateManager
and CTxMemPool classes over the next two commits.
This could also allow future tests that are only interested in the
internal behaviour of the classes to forgo instantiating the signals.
