This resolves part one of https://github.com/orgs/wixtoolset/discussions/9313 (I am the same person that wrote this ticket, but it's a different github account): wix extension remove extensionname/id just killed the full cache folder instead of deleting only the extension folder and thus removed all other extensions.

This is hopefully a trivial fix, but I also tried to improve diagnostics output, because currently, you enter the command and there is no feedback whether it was successful or not.

So I added a warning message that is written if the extension is not found, and I added a auccess message.

In case of a wrong extension reference specification, this is printed:

wix extension remove -g "WixToolset.Util.wixext/7.0.2"
WixToolset.Util.wixext : warning WIX6102: Extension WixToolset.Util.wixext with Id 7.0.2 not found in C:\Users\USERNAME\.wix\extensions\WixToolset.Util.wixext\7.0.2.

I case of success:

wix extension remove -g "WixToolset.Util.wixext/7.0.0"
wix.exe : information WIX6200: Removed extension folder C:\Users\USERNAME\.wix\extensions\WixToolset.Util.wixext\7.0.0

As there was a class ExtensionCacheWarnings, I added a similar class ExtensionCacheInformations. This is probably no good idea, as the message ids should not overlap. Maybe rename ExtensionCacheWarnings to ExtensionCacheMessages and name the methods with a Warning or Information prefix?

Hope you consider the idea of better feedback messages reasonable 😄 .

Is there anything else that I need to update? Unit tests?
