Embed++ 10d: Advanced intelliSense setup for MSVC's "Open folder"

If your embedded C++ project builds fine but IntelliSense complains—this episode is for you.

We’re tidying up loose ends from earlier episodes by aligning Visual Studio IntelliSense with the actual build system defined in your makefile. This includes centralizing environment variables, configuring CppProperties.json, eliminating Cypress IDE dependency, and verifying C++20 support across configurations.

You'll learn how to:
- Refactor your Makefile for cleaner environment handling
- Define CY_SDK_ROOT, ARMGCC_INSTALL_PATH, and CLANG_ROOT globally
- Ensure IntelliSense uses the right toolchain and flags
- Debug mysterious header resolutions and stale caches
- Properly configure include paths for both GNU C and C++
- Confirm C++20 features like constinit are recognized
- Build and navigate without relying on Cypress's IDE installation

✅ Bonus: You’ll also see how to verify proper header resolution with F12 and lock in full parity between build and IDE tooling.
