PSSA 1.19.0 settings

[bergmeister]

PR Summary

Pending PSSA 1.19.0 release and this PSES PR, but I tested it locally: PowerShell/PowerShellEditorServices#1280

• Split the powershell.codeFormatting.trimWhitespaceAroundPipe setting into 2 settings since PSSA has changed the behaviour of the current setting to only add the missing white space around pipes but not remove any more. For trimming of redundant whitespace a new settings was added in PSSA (this way it would not be breaking if someone used PSSA 1.19.0 with the current version of the extension). I could've applied something similar here and only added the new setting but for better naming, I decided to rename the setting powershell.codeFormatting.whitespaceAroundPipe to powershell.codeFormatting.trimWhitespaceAroundPipe, this is a breaking change, can we help the user point to the new setting? The new setting is powershell.codeFormatting.addWhitespaceAroundPipe and is disabled by default)
• Add new setting powershell.codeFormatting.whitespaceBetweenParameters (disabled by default)
• Add new None option for powershell.codeFormatting.pipelineIndentationStyle and make it the default. This new setting means that the formatter will not change the user's pipeline indentation so that the user has to explicitly opt-in, this was due community feedback.
