* [vcpkg] Refactor out abi_tags_from_pre_build_info()
* [vcpkg] Track Windows toolchain file in triplet hash
* [vcpkg] Improve error messages when constructing PreBuildInfo
* [vcpkg] Extract InstallPlanAction::BuildAbiInfo
* [vcpkg] Extract Build::EnvCache and private-impl VcpkgPaths
* [vcpkg] Enable compiler hash detection when binarycaching is enabled
* [vcpkg] Downgrade warning about missing ABI keys
When binarycaching is not enabled, this warning is spurious and provides no user value.
* [vcpkg] Cleanup
* [vcpkg] Refactor compiler tracking into triplet abi computation
Move several static global caches into VcpkgPaths/EnvCache.
Add feature flag 'compilertracking' to enable the new feature.
* [vcpkg] Refactor out PreBuildInfo::using_vcvars()
Move VcpkgTripletVar into build.cpp because it is not used outside that file.
* [vcpkg] Address some code analysis warnings

* [vcpkg] Add initial JSON support
This adds a JSON parser, as well as the amount of unicode support
required for JSON parsing to work according to the specification. In the
future, I hope to rewrite our existing XML files into JSON.
Additionally, as a drive-by, we've added the following:
* add /wd4800 to pragmas.h -- this is a "performance warning", for when
you implicitly convert pointers or integers to bool, and shouldn't be
an issue for us.
* Switched Parse::ParserBase to read unicode (as utf-8), as opposed to
ASCII
* Building again under VCPKG_DEVELOPMENT_WARNINGS, yay!
* [vcpkg] Consolidate several internal parsers together (packagespecs + logicexpression + control) and enhance error messages
* [vcpkg] Migrate Build-Depends parsing to new framework
* [vcpkg] Fix tests. Re-enable underscores in feature names due to libwebp[vwebp_sdl] -- todo: rename this feature and remove underscores.
