Add setting to better toggle block comments

Force block comment start (<#) and end (#>) to be on their own line and indent contents

When toggling a block comment the contents are not indented and if white space was not selected the start and end tags will not be on their own lines.
I propose a setting (or two) that would force a newline for the start and end tags and possibly indent the contents. This way when someone goes to toggle block comment it would already be pretty inline with outlined in https://github.com/PoshCode/PowerShellPracticeAndStyle.

Perhaps a dropdown with block comment style similar to the pipeline indentation style option.

I would like that when you toggle block comment that it matches the definition in https://github.com/PoshCode/PowerShellPracticeAndStyle/blob/master/Style-Guide/Documentation-and-Comments.md
This is to say the start and end tags on their own lines and the content indented once.

Appreciate any consideration to add this!

首先定位 PSScriptAnalyzer 中區塊註解切換的實作，以及現有的管線縮排樣式設定。將目前的行為與連結的 PowerShellPracticeAndStyle 指南進行比較。當所選設定能在切換註解時將 <# 和 #> 放在各自獨立的行上，並對區塊內容進行縮排時，即視為完成。
