Merge #117: cmake: Remove legacy MSVC build system

8d3bb2b cmake: Remove legacy MSVC build system (Hennadii Stepanov)
00b3061 cmake, docs: Update MSVC build docs (Hennadii Stepanov)
1c8ce0f fixup! cmake: Add preset for MSVC build (Hennadii Stepanov)

Pull request description:

  At this stage, the new CMake-based build system offers a comprehensive set of features, surpassing those of the legacy build system located in the `build_msvc` directory.

  As part of the transition to the new build system, the legacy MSVC build system has been removed.

  Additionally, a new ["Windows / MSVC Build Guide"](https://github.com/hebasto/bitcoin/blob/240309-cmake-BX/doc/build-windows-msvc.md) has been introduced, based on https://gist.github.com/hebasto/32c77c0cd592d13685437271ac6b79f6. Notably, the guide lacks information regarding the disabling of base address randomization (see bitcoin#21045). Even with `-DHARDENING=OFF`, this feature remains enabled by default.
