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 中块注释切换的实现以及现有的管道缩进样式设置。将当前行为与链接的 PowerShellPracticeAndStyle 指南进行比较。当所选设置能够在切换注释时将 <# 和 #> 放在各自单独的行上，并对块内容进行缩进时，即视为完成。
