.SYNOPSIS
Build and package PowerToys (CmdPal and installer) for a specific platform and configuration LOCALLY.

.DESCRIPTION
This script automates the end-to-end build and packaging process for PowerToys, including:
- Restoring and building all necessary solutions (CmdPal, BugReportTool, etc.)
- Cleaning up old output
- Signing generated .msix packages
- Building the WiX v5 (VNext) MSI and bootstrapper installers

It is designed to work in local development.
The cert used to sign the packages is generated by 

.PARAMETER Platform
Specifies the target platform for the build (e.g., 'arm64', 'x64'). Default is 'x64'.

.PARAMETER Configuration
Specifies the build configuration (e.g., 'Debug', 'Release'). Default is 'Release'.

.PARAMETER PerUser
Specifies whether to build a per-user installer (true) or machine-wide installer (false). Default is true (per-user).

.EXAMPLE
.\build-installer.ps1
Runs the installer build pipeline for x64 Release.

.EXAMPLE
.\build-installer.ps1 -Platform x64 -Configuration Release
Runs the pipeline for x64 Release.

.EXAMPLE
.\build-installer.ps1 -Platform x64 -Configuration Release -PerUser false
Runs the pipeline for x64 Release with machine-wide installer.

.NOTES
- Make sure to run this script from a Developer PowerShell (e.g., VS2022 Developer PowerShell).
- Generated MSIX files will be signed using cert-sign-package.ps1.
- This script will clean previous outputs under the build directories and installer directory (except *.exe files).
- First time run need admin permission to trust the certificate.
- The built installer will be placed under: installer/PowerToysSetupVNext/[Platform]/[Configuration]/User[Machine]Setup 
  relative to the solution root directory.
- To run the full installation in other machines, call "./cert-management.ps1" to export the cert used to sign the packages.
  And trust the cert in the target machine.
