c55584575a99ff565131207916eccb3223e508a3 cmake: Fix `FindQt` module (Hennadii Stepanov)
Pull request description:
This PR updates the `qt` package in depends to the latest open-source [6.8.3](https://www.qt.io/blog/qt-6.8.3-released) LTS release.
The update includes numerous bugfixes, which allows us to drop `qtbase_plugins_windows11style.patch`.
Additionally, it includes [patches](https://github.com/bitcoin/bitcoin/issues/34569#issuecomment-3892793262) for compatibility with GCC 16 (along with one extra patch), and incorporates a [commit](8f1b55d1d5) from https://github.com/bitcoin/bitcoin/pull/32709.
Closes https://github.com/bitcoin/bitcoin/issues/34569.

The patches needed to support this were dropped in
5e794e62024eef612e1fbb71c76ea54d17435c14 and "Cross-compiling does not
support LTO." (from #30997), so remove it for now.
Patch Qts internal libpng to resolve the failure.
I would like to have this patched, so we can continue working on the
removal of `FORCE_USE_SYSTEM_CLANG`. Otherwise builds will be broken using
the default clang (18) on the current Ubuntu LTS (24.04).
5deb0b024e14c7c63d405c651d1ca323560a1c21 build, test, doc: Temporarily remove Android-related stuff (Hennadii Stepanov)
Pull request description:
Previously, our Android builds were geared towards generating APKs, which relied on Qt. However, after migrating to C++20, compiling for Android became unfeasible due to Qt 5.15's compatibility limitations with NDK only up to r25, which includes an outdated embedded libc++ (see https://github.com/bitcoin/bitcoin/issues/29360).
All removed stuff will be reinstated after migrating the build system to CMake and upgrading Qt to version 6.x.
This PR makes possible a clean migration to the CMake-based build system as it removes code, which is not used at this moment.

The 32 to 64-bit time_t transition causes a build failure in the built-in
zlib about conflicting _TIME_BITS and _FILE_OFFSET_BITS.
Note that zlib doesn't use time_t at all, so it is a false alarm.
Take the following patch from upstream zlib:
a566e156b3.patch
Closes#29980.
I need to try and patch around Qts buildsystem to keep #21778 moving
along (the issue being that even when you tell Qt to build using
Clang on Linux, it still calls out to GCC, breaking our ability to have
a macOS release build env that doesn't have a GCC toolchain installed,
and thus no ld binary).
Before trying to patch Qt any further, update to the latest LTS
release, and update the current patch set.
The issue is that compilation is done with `x86_64-w64-mingw32-g++-posix`,
but then linking is done with `x86_64-w64-mingw32-g++`.
I'm guessing this has been broken since #24131
(01d1845a80ae48d741deea695ddce95d940ab0d8), but have not checked.
Fixes#29734.
Unblocks #29527 (now DEBUG=1 builds can be tested).
