Add ArgumentCompleter to Configuration parameter in BuildModules.ps1

[Copilot]

Description

Added [ArgumentCompleter] attribute to the $Configuration parameter in tools/BuildScripts/BuildModules.ps1 to enable tab completion for configuration options.

Changes:

• Added [ArgumentCompleter] with script block to provide tab completion for "Debug" and "Release" values

Impact:

• Tab completion now works: -Configuration <TAB> shows Debug/Release options
• More flexible than ValidateSet - allows future expansion of configuration options without code changes
• IntelliSense support in IDEs (VS Code, PowerShell ISE)
• Does not enforce strict validation, allowing custom configuration values if needed

Implementation:

[ArgumentCompleter({
    param($commandName, $parameterName, $wordToComplete, $commandAst, $fakeBoundParameter)
    @('Debug', 'Release') | Where-Object { $_ -like "$wordToComplete*" }
})]
[string]$Configuration = 'Debug',

Key Difference from ValidateSet:

• ArgumentCompleter: Provides tab completion suggestions but allows any value (flexible)
• ValidateSet: Enforces strict validation and rejects invalid values (restrictive)

Example:

# Valid usage with tab completion
./tools/BuildScripts/BuildModules.ps1 -Configuration Debug -TargetModule Accounts
./tools/BuildScripts/BuildModules.ps1 -Configuration Release -TargetModule Storage

# Tab completion: -Configuration <TAB> shows Debug, Release

Please make it an argument completer instead of validateset because there might be more options. @copilot

The -like operator is case-sensitive in PowerShell. This means tab completion won't work if a user types lowercase text like "deb" or "rel". Consider using the case-insensitive -ilike operator instead to provide a better user experience:

@('Debug', 'Release') | Where-Object { $_ -ilike "$wordToComplete*" }

Suggested change

	@('Debug', 'Release') | Where-Object { $_ -like "$wordToComplete*" }
	@('Debug', 'Release') | Where-Object { $_ -ilike "$wordToComplete*" }
