Merge bitcoin/bitcoin#30049: build, test, doc: Temporarily remove Android-related stuff

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for Android became unfeasible due to Qt 5.15's compatibility limitations with NDK only up to r25, which includes an outdated embedded libc++ (see https://github.com/bitcoin/bitcoin/issues/29360).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.
