Subject: [PATCH] vscode: point IntelliSense at clang instead of MSVC (#564)

* vscode: point IntelliSense at clang instead of MSVC

KYTY_SYSV_ABI expands to __attribute__((sysv_abi)) with no MSVC fallback,
which is correct for a project that rejects cl.exe at configure time. Nothing
told the C/C++ extension that, so it fell back to windows-msvc-x64 and
flagged every guest-facing function in the tree with "__attribute__ is not a
type name".

Set the IntelliSense mode, compiler path and C++ standard to match the
compiler the build actually uses, and export a compile database for it to
read.

* vscode: resolve the clang toolchain through the VS developer environment

The IntelliSense settings named a specific Visual Studio install, so the
compiler and Ninja only resolved on machines with VS 18 Community under
Program Files. Let CMake Tools source the developer environment instead,
which locates the toolchain through vswhere, and drop the explicit
compilerPath so cpptools takes the compiler from compile_commands.json.

Also point C_Cpp.default.compileCommands at the build directory this
workspace actually configures, and drop CMAKE_EXPORT_COMPILE_COMMANDS
because CMake Tools already exports the database by default.
