Add support for "fragment extensions"

[PankajBhojwani]

Support for fragment extensions, according to the implementation
outlined in #7584 (which calls them proto extensions.)

See #7584 for more information.

Validation Steps Performed

Self-testing by creating the folder
%LOCALAPPDATA%\Microsoft\Windows Terminal\Fragments
and adding a json file into it to modify and add profiles

Also self-tested with an app extension

Closes #1690

• Store Download

@PankajBhojwani @zadjii-msft I'm trying to use this feature with the latest preview release. I wanted to put all the color schemes in a separate json so as to not clutter the settings.json file. Not sure if that's valid/feasible or makes sense - let me know if it's not and I'll abandon. Reading the documentation, it's not clear to me where (path/folder) I would put this json extension file at? I believe I downloaded preview from github releases page if not from the Store - I'm not recalling with certainty now. Tried creating a file %LOCALAPPDATA%\Microsoft\Windows Terminal\Fragments\test.json but that didn't take effect as the schemes I put in there are not showing up. I'm probably doing something wrong I'm not sure. Thanks.

Pretty sure it has to be something like

%LOCALAPPDATA%\Microsoft\Windows Terminal\Fragments\MyCoolColorSchemes\test.json.

Tried it with no luck: %LOCALAPPDATA%\Microsoft\Windows Terminal\Fragments\test\test.json.

For the record, just adding the file, or modifying fragments, won't cause a "hot reload" of the settings - you'll need to touch the settings.json file, or relaunch the terminal to get the settings from the fragment

[damnskippy]

I relaunched the terminal for a good measure but still no joy.
I'm still convinced I'm doing something wrong :)

[zadjii-msft]

Oh you've got one too many braces in that scheme!

D'oh! That was it! Thanks so much for your time and kindness (and good eyes!).
As a punishment, I'm disqualifying myself from ever getting into yaml vs json debates for the next 6 months.

Is there some docs for how to make, build and publish on the Windows Store an extension that adds a single JSON fragment?

Is there some docs for how to make, build and publish on the Windows Store an extension that adds a single JSON fragment?

@NatoBoram Found this: https://docs.microsoft.com/en-us/windows/terminal/json-fragment-extensions
Does that help?

[NatoBoram]

Not really. This assumes I have an app where I can stick this JSON fragment, but I don't. I want to make an app that's only a JSON fragment. Once I have created a folder that contains this mysterious Package.appxmanifest and the Public/Fragments/theme.json file, how do I compile that? How do I publish it? What's the command I need to run to make this into an installable package?
