build: ship a Win11 build of Terminal that's <=half the size (#12560)

Four (4) squashed changes, with messages preserved.

## release: move symbol publication into its own phase

Right now, symbol publication happens every time we produce a final
bundle. In the future, we may be producing multiple bundles from the
same pipeline run, and we need to make sure we only do *one* symbol
publication to MSDL.

When we do that, it will be advantageous for us to have just one phase
that source-indexes and publishes all of the symbols.

## Remove Terminal's built-in copy of the VC Runtime

This removes the trick we pulled in #5661 and saves us ~550kb per arch.

Some of our dependencies still depend on the "app" versions of the
runtime libraries, so we are going to continue shipping the forwarders
in our package. Build rules have been updated to remove the non-Desktop
VCLibs dependency to slim down our package graph.

This is not a problem on Windows 11 -- it looks like it's shipped inbox.

**BREAKING CHANGE**: When launched unpackaged, Terminal now requires the
vcruntime redist to be installed.

## Prepare for toggling XAML between 2.7.0 and -prerelease on Win11

common.openconsole.props is a pretty good place to stash the XAML
version since it is included in every project (including the WAP
project (unlike the C++ build props!)).

I've gone ahead and added a "double dependency" on multiple XAML
versions. We'll toggle them with a build flag.

## Run the release pipeline twice, for Win10 and Win11, at the same time

This required some changes in how we download artifacts to make sure
that we could control which version of Windows we were processing in any
individual step.

We're also going to patch the package manifest on the Windows 11 version
so the store targets it more specifically.

On top of the prior three steps, this lets us ship a Windows 11
package that costs only ~15MB on disk. The Windows 10 version, for
comparison, is about 40.

   <!-- This is magic that tells msbuild to link against the Desktop platform

        building a true universal "app", we're building a desktop application
-       with xaml. APIs like CreatePseudoConsole won't always be linkable without Desktop platform,
+       with xaml.
-       but we now carry our own copy of them in the winconpty library which works everywhere.
-       For future reference, _VC_Target_Library_Platform can be configured to say which CRT to link against.
-       Now that this doesn't say anything, the implicit is 'Store' which links against the App CRT.
-       The alternative is 'Desktop' which links against the usual CRT redistributable.
        Linking against the App CRT will require the VCRT forwarders to be dropped next to the final binary for
        desktop situations, but it will let non-desktop situations work since there is no redist off desktop.
        The forwarders can be found at https://github.com/microsoft/vcrt-forwarders and are already included
        in our CascadiaPackage project.
