Added scripts and projects to create self-extracting installer on Windows

[5656hcx]

Add Windows driver installer tool and build pipeline

Summary

This PR introduces a complete Windows driver installation solution: a native qdinstall tool for low-level driver management, a self-extracting C# installer executable for end-user distribution, and the build scripts that tie everything together for x86, x64, and arm64 platforms.

Changes

1. New: qdinstall tool (src/windows/tools/qdinstall/)

A native C++ command-line utility for driver lifecycle management:

Flag	Action
-i	Install — removes stale drivers via qdclr.exe, installs all .inf drivers using pnputil, triggers device re-enumeration, and registers the installation in the Windows registry (Add/Remove Programs).
-x	Uninstall — cleans the DriverStore via qdclr.exe, removes registry entries, and re-enumerates the device tree.
-v	Show package version and currently-installed version from registry.
-g	Print the registered installation path.
-p <path>	Specify the installation directory (used by the outer installer).

• Supports x86, x64, and arm64 platforms.
• Registers under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Qualcomm USB Drivers.

Files: main.cpp, main.h, registry.cpp, registry.h, qdinstall.sln, qdinstall.vcxproj

2. New: Self-extracting installer (build/build-installer.ps1)

A PowerShell script that:

1. Packages the payload — stages target/Drivers/ and target/Tools/ into a zip, promoting qdclr.exe and qdinstall.exe to the payload root for direct execution.
2. Compiles a C# self-extracting EXE — embeds the payload zip as a .NET manifest resource and compiles via csc.exe (Framework 4.0). The resulting executable:
   • Supports --install (default), --uninstall, and --version flags.
   • Auto-elevates to administrator via UAC (runas verb).
   • On install: extracts payload to a temp directory, uninstalls legacy packages (qualcomm_userspace_driver, qud, qud.slt, qud.internal) via qpm-cli, runs qdinstall.exe -i -p <installPath>, then copies all files to %ProgramFiles%\Qualcomm\Qualcomm USB Drivers.
   • On uninstall: reads the uninstall command from the registry, executes it, and deletes the installation directory.
3. Reads version from src/windows/qcversion.h and stamps it into the assembly metadata.

3. New: Build scripts (build/)

Script	Purpose
build_tools.ps1	Builds all tool projects (qcdev, qdcfg, qdclr, qdinstall, wwansvc) via MSBuild with auto-detection of Visual Studio. Supports platform-specific fallback (e.g., x86-only tools build as x86 regardless of target).
build-installer.ps1	Assembles payload and compiles the C# self-extracting installer (see above).
build_installer.bat	Top-level orchestrator — loops over x86/x64/arm64, invokes build_tools.ps1, build-installer.ps1, and sign.ps1 for each architecture. Produces qcom_usb_kernel_drivers_{x86,x64,arm64}.exe.

4. Renames

• build_all.bat → build_drivers.bat (clarifies scope — driver .sys/.inf build only)
• build.ps1 → build_drivers.ps1 (same)

Install Flow

qcom_usb_kernel_drivers_x64.exe (C# self-extractor)
  → UAC elevation
  → Extract payload.zip to %TEMP%
  → Uninstall legacy packages via qpm-cli
  → Run qdinstall.exe -i -p "%ProgramFiles%\Qualcomm\Qualcomm USB Drivers"
      → qdclr.exe (remove old DriverStore entries)
      → pnputil /add-driver *.inf /install /force
      → Device tree re-enumeration
      → Registry registration (Add/Remove Programs)
  → Copy payload to install path

Uninstall Flow

qcom_usb_kernel_drivers_x64.exe /uninstall, or uninstall from control panel
  → UAC elevation
  → Fetch uninstall string from registry
  → Run qdinstall.exe -x
      → qdclr.exe (remove DriverStore entries)
      → Remove registry registration
  → Delete the installation directory

Testing

• Built installers for all three architectures.
• Verified install and uninstall flows on Windows.
