Enable enforcing consistent casing

Summary of the new feature

PowerShell code used in official examples and VS Code code generation seems to follow some basic casing conventions:

• PascalCase for
  • cmdlets
  • parameters
  • constants
• lowercase for
  • operators
  • statements (if, foreach, etc)
• camelCase for
  • local variables
• casing of module names and .NET types, enum values, etc consistent with their original case-sensitive casing

I would like to optionally enforce these casing conventions with PSScriptAnalyzer.

Proposed technical implementation details (optional)

I would like to enable rules in my PSScriptAnalyzerSettings.psd1 that enforce the casing rules above and autofix casing issues.

What is the latest version of PSScriptAnalyzer at the point of writing
1.18.2

首先檢視 issue 中提出的大小寫慣例，以及 PSScriptAnalyzer 設定如何啟用規則。完成的內容應包括對所列大小寫類別的選擇性強制執行和 autofix 支援，並定義對保留原始大小寫的模組名稱以及已定義 .NET 型別的行為。
