WIP: Switch appveyor build from Release to Debug #20392

As per brief discussion. Visual Studio 2019 and Appveyor images have recently been updated. While it's only a minor update that doesn't break ABI compatibility it does seem to have broken compatibility for Release builds. This apparently occurs if compiler optimisations are turned on.

This PR switches the Appveyor CI job from a Release build to a Debug build in order to fix the CI failures.

Subsequent to this PR I will commence a new build of the Qt static libraries with the latest Visual Studio 2019 toolset so that release build can work again.

From past experience the msvc compiler can be quite aggressive regarding access to uninitialised/unallocated memory on debug builds. The unit test failure on caddrdb_read_corrupted is likely due to a debug-only assert.

The choices that occur to me are:

  • Continue building as a Release build and update the pre-compiled Qt libraries for VS2019 v16.8.1.

    • Pros:
      • Unit tests will pass
    • Cons:
      • The same ABI incompatibility is likely to occur again for a future VS minor release. In the time Bitcoin Core has been using Appveyor (approx. 2 years I think) this is the first case.
      • New Qt 5.9.8 build required.

  • Switch to a Debug build.

    • Pros;
      • ABI compatibility for VS 2019 minor releases should be preserved since debug builds do not use compiler optimisation flags which are only guaranteed to be compatible for libraries built with identical Visual Studio versions.
    • Cons:
      • Need to fix or disable unit tests causing debug asserts.

Closing this PR as I've managed to get the msvc release build working again. Will open a new PR for that.

Pull request description:

  The motivation for this PR is twofold:

    1. Update the Qt binaries used by the appveyor CI job after a recent update to Visual Studio 2019 used in the Appveyor build image resulted in ABI incompatibilities,

    2. Remove optimisations and debug information from the Bitcoin Core `Release` msvc build to reduce the chance of future ABI incompatibility issues for future Visual Studio updates.

  The changes made in this PR are:

   - Changed appveyor config file hash to use a new version of Qt pre-compiled binaries built for Visual Studio 2019 v16.8.1.
   - Adjusted msvc compiler and linker settings to remove optimisations and debug information generation to help avoid future ABI issues on Visual Studio updates.
   - Tidied up debug and release configuration blocks in common project file to avoid duplication.
   - Updated appveyor config to use latest Visual Studio 2019 image.
   - Bumped vcpkg version to tag `2020.11-1` for binary caching feature*.

  See #20392 for related discussion.

  *Binary caching is a new [vcpkg feature](https://github.com/microsoft/vcpkg/blob/master/docs/specifications/binarycaching.md) that allows dependency caching. This PR is not using the feature but by updating the vcpkg version it means it can be optionally used by other contributors in their own Appveyor configs. By caching the vcpkg dependencies using this feature my build times are reduced by approx 10 minutes.
