ci: Set MSVC toolset version explicitly #28934

   This PR is an alternative to #28905 and reverts it.

   To avoid toolset version incompatibilities, which result in errors like this:

   0LINK : fatal error C1900: Il mismatch between 'P1' version '20230904' and 'P2' version '20221215' [D:\a\bitcoin\bitcoin\build_msvc\test_bitcoin\test_bitcoin.vcxproj]
   1LINK : fatal error LNK1257: code generation failed [D:\a\bitcoin\bitcoin\build_msvc\test_bitcoin\test_bitcoin.vcxproj]
   2LINK : fatal error LNK1327: failure during running link.exe [D:\a\bitcoin\bitcoin\build_msvc\test_bitcoin\test_bitcoin.vcxproj]
   

   it is enough to set it explicitly in the vcpkg triplet file (see the second commit). The VCToolsVersion environment variable is set by the ilammy/msvc-dev-cmd action.

   Please note that the #28905 is not optimal:

   I guess this is something we’ll just have to maintain forever? That’s a shame, because it also adds ~30% runtime to this CI job.

2. ci: Run vcpkg with path prefix

   The GHA VS installation includes its own vcpkg package manager, which is
   available since VS 17.6. This change avoids any ambiguity about which
   copy of vcpkg we run.

   Does the CI job still cache the vcpkg dependencies? Will this PR still work if there a minor version update on the build image?

    It does.

    Will this PR still work if there a minor version update on the build image?

    I’ve added the toolset version to the cache key: https://github.com/bitcoin/bitcoin/blob/70100f8584c762cbc6cbc09d05cc4e9d22a3ec75/.github/workflows/ci.yml#L250

    so the cache will be invalidated if it is changed.

    Seems fine to do this, if this makes CI faster and there are no major downsides
